Fleetwood Excursion Tire Upgrade Guide: 255 to 275 Width Conversion

After upgrading my 2015 Fleetwood Excursion M-35B from 255 to 275 width tires, it started getting sketchy handling on highway turns. The current 255/70R22.5 tires are wearing out and I'd love to go wider with 275/70R22.5 for better stability, but I keep getting conflicting advice from different tire shops.

Some say it's fine, others warn about clearance issues and potential problems. I really need to know what specific measurements I should check before making this change. What wheel width do I need? How do I verify there's enough steering clearance? I don't want to buy expensive tires only to find out they don't fit properly or aren't safe for my RV's load requirements. …more

Ford E-350 vs E-450 RV Chassis: Fuel, Power & Weight

Last weekend I felt this awful engine strain and heard sluggish acceleration sounds while test-driving a 2017 Phoenix Cruiser #2351 with its E-350 chassis and V10 engine. I'll be doing extensive western touring through mountain and plains regions, which means substantial mountain grades and wind challenges. I'm comfortable driving slowly and want to understand two key things: 1) Will this E-350 chassis handle mountain grades without major issues, and 2) What's the real-world fuel consumption like? I plan to do an initial inspection this weekend, followed by a third-party mechanical review. I'm not overly concerned about fuel economy but want to understand the actual performance limitations. I'd appreciate insights from owners who have experience with similar touring conditions on an E-350 chassis. …more

Michelin RV Tire Age: Inspect After 5 Years, Replace by 10

Called three different tire shops this month about my 2020 Newmar Ventana's Michelin 275/70R22.5 tires and all want them replaced just for being 6 years old despite perfect tread. I'm meticulous about tire maintenance - I check air pressure religiously before and after every trip, whether it's a short weekend getaway or an extended cross-country journey like the 5000-mile trip I just completed.

Despite my careful maintenance routine, I experienced a blowout on the right rear inside tire during the final leg of that recent long trip. When the roadside service technician came out to help, he recommended replacing all six tires specifically because of their age, even though the remaining tires still have plenty of tread depth and appear to be in excellent condition visually.

This has me confused because I've heard conflicting advice from other RV owners - some say well-maintained motorhome tires can safely last up to 10 years, while others insist on much shorter replacement intervals. I'm trying to understand what the actual safety guidelines are for RV tire replacement based on age versus tread wear. Should I really replace tires that still look good just because of when they were manufactured? What's the real story on how tire age affects safety, and how do I properly check the manufacturing date to make this decision? …more

When to Replace RV Tires by Age: Inspect at 5, Replace by 10

Pulled into three different tire shops asking about RV tire replacement and got three completely different answers about when tires actually need replacing. The unit has six tires with 2018 DOT date codes, making them 7 years old as of 2025. Mileage is approximately 28,000 miles, and visual inspection shows good tread depth with no apparent cracking, bulging, or other visible deterioration.

A tire technician who performed my state inspection indicated the tires appear serviceable from an external assessment standpoint. However, I understand there may be internal degradation factors not visible during standard inspection procedures.

What is the technical consensus on replacement timing for RV tires when age limits are reached but visible condition remains acceptable? Specifically looking for guidance on the 6-7 year replacement interval and whether internal rubber compound deterioration poses legitimate safety risks regardless of external appearance. …more

RV Flat Tire on Highway: Emergency Steps & Specialized Roadside Service Tips

Every highway mile seems to be eating through my Tiffin Allegro motorhome tires way faster than it should, especially after that brutal double blowout on the back axle. When this happened to us, we found that regular AAA and typical roadside assistance don't always help with RVs. We were stranded and eventually had to use a service called Driving Solutions, who charged us $1600 for used tires after eight hours of waiting.

What's the proper procedure if this happens? Should I try to move to a safer location first, or stop immediately? Who should I call for help - are there specialized services that handle RV tires? I want to be prepared with the right contacts and know the safe steps to take, because I imagine regular tow trucks and tire services might not have the equipment or expertise to handle a large motorhome tire emergency on the interstate. …more

Ford E350 Dually Wheel Center Hole Size Guide: Front vs Rear Differences Explained

According to my mechanic, my Ford E350 dually has mismatched wheel fitments, center holes that don't align properly, AND different sizing between front and rear wheels all at once. I have a 2001 Ford E350 Class C motorhome with dual rear wheels, and I desperately need to get a spare tire sorted out.

I found what I thought was the perfect rim - same bolt pattern as my existing wheels - but when I got home and really looked at it, the center hole is noticeably smaller than the ones currently on my RV. I've been assuming all six rims on a dually setup would be identical, but now I'm second-guessing everything.

Could it be that Ford actually uses different center hole sizes between the front wheels and rear dually wheels on the E350? I'm really hoping someone can clarify this because I need to know if I bought the wrong type of rim or if there's something else I'm missing here. …more

SDI E-Clik vs Liquid Spring: Affordable F53 Chassis Suspension Upgrade Options

Nobody warned me that what started as minor swaying on highway trips last month would turn into white-knuckle driving every time I take my F53 chassis RV over 50mph. SDI E-Clik costs about a third of what Liquid Spring systems run, but I'm wondering what you actually get for that price difference.

Is E-Clik just electronic shock control, or does it offer more comprehensive suspension improvements? How does the ride quality compare between the two systems on F53 motorhomes? …more

Installing a Rear Camera on Your Fifth Wheel RV: Complete Guide

I spent way too much time backing into spots blind, so I grabbed my tools and I'm ready to install a rear camera system on my fifth wheel myself — just need to know the best place to start. I keep hearing horror stories about people drilling holes in the wrong spots or having wiring issues that cause leaks or electrical problems.

I'm torn between wireless and wired systems - which is actually safer to install? And I'm terrified about where to mount the camera without damaging my RV's structure or creating water intrusion issues. Should it go at the top center or would a corner placement be less risky?

I've been looking at brands like Furrion, Haloview, and Rear View Safety, but I need to know which ones are most reliable and forgiving for a cautious DIYer. Most importantly, how do I run cables safely without creating new holes that could leak? Are there existing entry points I should use instead?

(Note: Can you share details about your current fifth wheel and any existing camera/monitoring setup?) …more
2003 Ford F53 Wheel Bearing Grease: Best Products

2003 Ford F53 Wheel Bearing Grease: Best Products

I'm wondering if my grease choice is wrong for my 2003 Ford F53's front bearing replacement when my neighbor's identical motorhome runs perfectly after his service. The original grease that came out was a dark gray/black color and while there wasn't any catastrophic damage, the races showed enough wear marks that I decided to replace everything while I'm in there.

I've been researching different options and keep seeing conflicting recommendations. Some people swear by standard lithium grease, others recommend full synthetic formulations, and I've even seen mentions of specific brands like Valvoline MaxLife and Timken. I know the F53 chassis carries significantly more weight than a typical pickup truck, so I want to make sure I'm using something that can handle the load.

I have the torque procedure down (30 ft-lbs initial, back off, then final setting at 17 in-lbs), but I want to make sure I'm pairing that proper installation with the right grease. What specific grease products work best for the F53 front wheel bearings, and are there any compatibility issues I should be aware of when selecting a replacement grease? …more
Ford E-450 RV Shock Upgrade: Bilstein 4600 vs Koni FSD

Ford E-450 RV Shock Upgrade: Bilstein 4600 vs Koni FSD

Before spending hundreds on new tires and suspension parts for my 2023 Ford E-450 Class C motorhome, the ride quality is still absolutely brutal. The RV is about 28 feet long and weighs approximately 14,500 pounds loaded. We use it primarily for family camping trips, but I also occasionally tow a small utility trailer with dirt bikes - probably 25% of our trips involve towing that extra 2,000-3,000 pounds.

I've been researching shock absorber upgrades and have narrowed it down to two main options that seem popular in the RV community: the Bilstein 4600 series and the Koni FSD (Frequency Selective Damping) shocks. I understand both are significant improvements over stock, but I'm trying to understand the practical differences between them for my specific setup and usage patterns.

What I really need to know is which option provides the best balance of ride comfort improvement, handling stability (especially when towing), and overall value for money on the E-450 chassis. I want to make sure I'm making the right choice since this is a fairly significant investment and I don't want to have buyer's remorse later. …more

Toyo vs Michelin RV Tires: Complete Comparison for Diesel Pusher Motorhomes

Planning to replace the tires on my 2019 Tiffin Phaeton 40IH, and ever since I started getting quotes, everyone keeps suggesting Toyo as a cheaper alternative to Michelin.

I'm honestly a bit overwhelmed by all the tire choices and wondering if I'd be making a mistake switching brands. Will Toyo tires give me the same ride quality as the Michelins? I've heard you can save quite a bit of money, but I don't want to compromise safety or comfort since we're still learning how to handle this big rig.

Would really appreciate some guidance from those who've made this switch - are you happy with the decision or do you regret not sticking with Michelin? …more

F53 Hydroboost Brake System Problems: Complete Repair & Troubleshooting Guide

Between the small hydraulic leak that started on my 1995 F53 hydroboost brake system last month and what's happening now, I'm wondering how much worse this nightmare can get. Right now it's just a slow drip - maybe one drop per minute - and I can feel the power steering is slightly stiffer than normal, plus the brake pedal requires a bit more effort than usual.

What I really need to understand is the theory behind how hydroboost systems operate, since this is different from the vacuum brake boosters I'm used to. More importantly, if this leak gets progressively worse and I don't address it immediately, what's my worst-case scenario? Will I completely lose power steering and power braking assistance, or would I still have manual control of both systems? I'm trying to figure out whether this is something I need to drop everything and fix right now, or if I have some time to plan the repair properly. …more

Which Dually Tire for RV Leveling Blocks? Inner vs Outer

My Class A sits crooked when parked in front of my house due to the road crown, and the entry steps won't extend because they hit the curb. I built some wooden ramps from stacked 2x8s to level out the passenger side, but they're only wide enough for one tire. My neighbor insists I should use the inner dually tire since it carries more weight, but the RV dealer told me to always use the outer tire for stability. Meanwhile, YouTube videos show people doing it both ways. The road slopes toward the curb, so using the inner tire would actually put me higher up the crown. I've been defaulting to the outer tire thinking it keeps things more consistent, but now I'm second-guessing myself. Which dually tire should actually go on the leveling blocks? …more

RV Water Crossing: How to Avoid Engine Damage and Recovery Steps

Woke up to my Winnebago Ekko surrounded by floodwater above the wheel hubs, the engine is completely dead, AND there's moisture creeping into places it definitely shouldn't be. While I haven't noticed any unusual noises or driving behavior, I want to be proactive about potential water exposure damage.

I've checked that the oil isn't milky and brake fluid looks normal. However, I'm concerned about potential impacts on hubs, bearing grease, brake fluid, differential fluid, and transmission fluid from this water exposure.

Has anyone else with an Ekko experienced similar flooding and have recommendations for post-water exposure inspection? Am I being overly cautious about checking various components? I'm hoping to get some expert advice on what specific things I should examine to ensure no long-term damage occurred. …more
