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

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

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

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

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

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

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

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
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

How to Protect Your RV Alternator When Charging Lithium Batteries: DC-

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

Ford F53 Chassis Firewall Wiring: Finding Brake LED Through-Holes

Opened up my 2022 Holiday Rambler 36DB for spring prep and once again I'm staring at my 2021 Ford F53 chassis firewall wondering where those brake LED through-holes are hiding. I need to run the brake indicator LED wire from my toad to the dashboard inside the motorhome, but I'm having trouble locating the best firewall penetration point.

Rather than drilling a new hole through the firewall (which I'd prefer to avoid for obvious reasons), I'm hoping to find an existing through-hole or grommet that I can utilize. I've heard that Ford F53 chassis typically have several factory access points, but I'm not sure exactly where to look or which ones would be most suitable for this type of low-voltage wiring installation.

Can anyone provide specific guidance on where to find existing firewall through-holes on the F53 chassis that would work well for routing brake indicator wiring? I want to make sure I'm using an appropriate location that won't interfere with existing systems and will provide a clean, professional installation. …more

RV Dash AC Blower Motor Not Working? Check These Hidden Fuses First

Last week I'm trying to decide between shelling out hundreds for an RV tech or tackling this myself after my F53 chassis motorhome's dash A/C blower motor completely died. I've checked all the obvious fuses in the main fuse panels, but nothing seems blown.

I discovered something crucial that might help others: Fleetwood added a hidden 25 amp fuse wire-tied above the emergency brake, not shown in standard Ford chassis diagrams. In my case, this was the culprit. As a temporary fix, I even ran a wire directly from my lighter plug with a switch to get some air movement.

I'm wondering if other RV owners might have similar hidden electrical components that aren't in standard chassis wiring documentation? Before taking it to a shop, I recommend carefully checking behind panels and tracing wires, especially looking near the dashboard area above the emergency brake for manufacturer-specific fuses. …more

RV Auto Hold Parking Brake: Complete Guide to Operation and Troubleshooting Basics

Woke up this morning and spotted my 1999 Damon Daybreak 3270's auto hold parking brake light blinking on the dash when it was perfectly fine yesterday. I'm still learning everything about motorhome systems and I'm confused about the auto hold parking brake feature.

The system doesn't seem to be working properly (barely holds at all), but honestly I'm not even sure I understand how it's supposed to operate in the first place. Is this something that engages automatically? Do I need to do something specific to activate it?

Could someone explain how these auto hold parking brake systems work on motorhomes, how to use them properly, and maybe some troubleshooting tips? I want to make sure I understand the basics before I start trying to fix anything. …more

Ford F53 V10 Bypass Oil Filter Installation: Best Mounting Locations for RV Chassis

Ford F53 V10 Bypass Oil Filter Installation: Best Mounting Locations for RV Chassis

Walked out to check my oil analysis results and they're showing 15-micron contaminants, but everything says my 2003 F53 V10's factory filter catches down to 25 microns. I've been reading about how these can help extend oil life and keep things cleaner, but I'm honestly not sure where the best place to mount one would be.

I've seen some people mention sandwich adapters at the original filter location, remote mounting blocks, and even tapping directly into the engine block. As someone who's still learning, I don't want to mess this up or create problems down the road. What's considered the best practice for mounting location on the F53 V10? I'd really appreciate some guidance from those who have done this before. …more

Ford F53 Godzilla V8 Suspension Problems: Fixes & Upgrades for Class A Motorhomes

Halfway through my first long trip, this bone-rattling vibration and unsettling sway started plaguing my newer Class A motorhome with the Ford F53 Godzilla V8 chassis. Coming from a 26' travel trailer and a history with brands like LazyDaze, I'm trying to understand the current RV landscape. I saw a Baystar 2023 model where the owner spent around $35,000 on suspension upgrades after just 12,000 miles.

Sounds awesome on paper, but I keep hearing people say you still need to dump a ton of money into suspension upgrades to make these things handle decently on the highway. Did Ford actually improve the suspension setup when they introduced the Godzilla engine, or are we dealing with the same basic chassis design that's been around forever? I'm talking about 30+ foot Class A rigs here - seems crazy that a $200k motorhome would need immediate aftermarket work to drive safely.

Anyone know if the Godzilla F53 combo actually fixed the handling problems or if it's just more power on the same wobbly platform? …more
