Ford E450 Inertia Switch Location Guide - Find Your RV's Fuel Cutoff Reset Point

Ford E450 Inertia Switch Location Guide - Find Your RV's Fuel Cutoff Reset Point

Every Ford E450 I've worked on had the inertia switch behind the driver's panel — but my 2011 Freedom Elite 32r has it hidden somewhere completely different. The engine is experiencing what appears to be fuel delivery issues after a minor fender bender, and I suspect the inertia switch may have been triggered and needs to be reset.

I've already done extensive searching in the typical locations - removed both driver and passenger side kick panels completely, pulled out the glove box, and even partially disassembled sections of the dashboard. Despite checking all these common spots where Ford usually places these switches, I'm coming up empty-handed.

Could the switch be integrated into another component on this particular year and model? Are there any alternative locations specific to the E450 chassis or Freedom Elite configuration that I should be checking? I'm also wondering if some models of this year might not have a traditional standalone inertia switch at all. …more

RV Liquid Spring Adjustment Guide: Setup & Tuning Tips

Three different adjustment knobs on my 2022 Tiffin Open Road 34PA's LiquidSpring suspension and I'm staring at them with zero clue about the limits.

I've got LiquidSpring suspension on all four corners, but I'm specifically wondering about the rear struts. Can I raise and lower just the rear ones independently, or am I stuck adjusting everything at once like some kind of suspension caveman? I'd love to dial in the perfect ride height and handling, but I need to know if I can fine-tune the back end separately from the front. Between the control panel and what I assume is some fancy smartphone app, surely there's a way to make this old road warrior ride like a dream without turning into a mechanical engineer, right? …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

Monaco Diplomat Rear Air Suspension Won't Dump Fully - Troubleshooting Guide

Last week my 2006 Monaco Diplomat's rear air bags started refusing to dump all the way down when I hit the air dump before leveling. The front dumps fine, but the back stays partially inflated.

I'm still pretty new to RV maintenance and not sure where to start troubleshooting this. Should I be hearing air escaping when I activate the dump? What are the most common causes when rear air bags won't dump completely? Any guidance on what to check would be really appreciated! …more

ECM Low Battery Warning RV: Complete Diagnosis & Fix Guide

During a family trip, my 2005 Fleetwood Discovery 39S threw code 168-1 for low ECM battery voltage and went into full shutdown mode—is this dangerous with kids onboard? Engine cut out, transmission selector went dark, ABS warnings everywhere - the whole nine yards. Scared the heck out of me when it happened on the interstate!

I'm seeing this seems to be a thing with these diesel pushers, but I'm drowning in conflicting info online. Some say it's the chassis battery, others blame alternator issues, and I've even seen posts about ECM power supply problems on the Caterpillar engines. What's the actual step-by-step process to track this down? And more importantly, how do I fix it so it doesn't leave me stranded again? Really need a complete walkthrough of what causes this code and the proper repair approach. …more

Protect Your RV Alternator When Charging Lithium

Tried everything my neighbor did to charge his LiFePO4 batteries but mine keeps frying the alternator while his works flawlessly — what's different? I want to install a temperature sensing device that can interrupt charging by opening the solenoid between chassis and house charging systems if the alternator gets too hot. I'm looking to spec out components and understand the installation process, and I'm open to hearing why this might not be a good approach. My goal is preventing alternator overheating when these lithium batteries draw high current compared to my old flooded or AGM batteries. I'm looking for technical feedback and am totally open to critique. …more

RV Storage on Gravel: Preventing Weed and Moisture Issues

RV Storage on Gravel: Preventing Weed and Moisture Issues

Nobody warned me that buying a house with RV storage meant inheriting the previous owner's 13-year-old weedy, muddy gravel disaster. While considering this location's storage options, I want to mitigate potential issues with weed growth and moisture retention under the RV.

I'm seeking advice on effective strategies for storing on a gravel surface that shows significant weed penetration and moisture retention. Initial ideas include pre-treatment herbicide application and installing a protective barrier, but I want input from experienced RV owners.

My primary concerns are preventing undercarriage damage and managing moisture/vegetation growth. I plan to spray weed killer beforehand and potentially lay down a weed barrier, pending facility approval. What techniques or materials do you recommend to protect my RV during storage? …more

RV Engine Stalling & Transmission Issues - Diagnosis Help

Replaced multiple parts but I'm still standing in the auto parts store aisle staring at diagnostic tools with no clue which one I actually need for my RV's stalling and transmission issues. When I'm cruising and let off the gas, sometimes the RPMs drop like a rock, other times they just hang there until I slow down more. That's weird enough, but here's the real kicker - every now and then the whole engine just dies on me when I'm rolling up to a stop sign or red light. Maybe happens twice in 600 miles or so, so it's not constant but definitely not normal either.

I'm wondering if these two issues are connected somehow? Like could whatever's causing the stalling also be messing with how the transmission acts when I let off the throttle? Really hoping someone has seen this combo before because I'm in Germany and finding RV-specific help is tough.

I'm looking for any insights from folks who might know what could cause this - hoping to get to the bottom of this before it becomes a bigger problem! …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

RV Hydraulic Leveling Jack Leaks: Normal Seepage vs Serious Problems Explained

Somewhere between parking and leveling my 2019 Forest River Georgetown, I noticed the hydraulic leveling jacks have small amounts of fluid on the fittings. No puddles underneath and the jacks aren't sagging when stored or in use. Just a light coating on the hoses and one fitting has a small amount of fluid visible.

Is this normal seepage or something I should worry about? What's the difference between normal weeping and a real problem that needs immediate attention? …more

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

RV Transmission Problems: Troubleshooting Guide & Quick Fixes

Planning to fix my Class A motorhome's transmission myself, but my neighbor says it needs fluid, the dealer insists it's the torque converter, and YouTube swears it's the solenoid pack. On my 4R100 transmission specifically, the transmission has been shifting a little rough lately, especially when accelerating from a stop or when climbing hills. Sometimes it seems to hesitate before shifting into the next gear, and I've noticed the engine RPMs climbing higher than usual before it finally engages.

I've owned this RV for about three years now, and I'll admit I haven't been as diligent about transmission maintenance as I probably should have been. The fluid looked a bit dark the last time I checked it, but I'm not entirely sure what I should be looking for or what the proper procedure is for checking transmission health. I've heard horror stories about transmission rebuilds costing thousands of dollars, so I want to make sure I'm approaching this systematically rather than just hoping the problem goes away.

What's the proper first step when you suspect transmission problems? Should I be taking it straight to a shop, or are there some basic diagnostic steps I can handle myself before spending money on professional diagnosis? I want to make sure I'm not missing something simple that could save me a lot of headache and expense down the road. …more

How to Replace Obsolete F53 Chassis ABS Control Module - Ford Discontinued Repairs Guide

Last week my 2013 Coachman Encounter's F53 chassis started throwing ABS codes — can't afford the $3,000+ dealer quote so is there a DIY fix under $500? Our ABS control module failed, creating a no brakes issue. After being towed to a Ford Dealership on May 28th, the repair has been incredibly complex. They've received incorrect and damaged modules, and even after claiming to fix it, the ABS warning light remains on and reprogramming attempts have failed.

Ford apparently no longer makes this module for units over 10 years old. What alternatives exist for finding a compatible ABS control module for my older F53 chassis when OEM replacement isn't available? …more
