RV AC Making Loud Humming Noise? Fix Compressor Not Starting

Somewhere above my head, there's this loud, relentless humming grinding through the RV whenever I flip on the rooftop AC — compressor won't start but the fan spins fine.

I've been dealing with this for days now and it's driving me crazy - especially with the heat we've been having! The humming is so loud that I'm worried something might be seriously damaged. I really hope this is something I can fix myself rather than having to call out a repair tech. What could be causing a compressor to hum loudly but not start up? …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
Ford E-450 RV Shock Absorber Upgrade Guide: Bilstein 4600 vs Koni FSD

Ford E-450 RV Shock Absorber Upgrade Guide: 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

Cummins ISL Code 1896: EGR Valve Controller Gaskets & Repair

About to drop $2,800 on my Cummins ISL throwing code 1896 for EGR valve controller out of calibration and wondering if I can tackle this myself. Planning to pull and clean the EGR valve controller to see if that clears it up.

Do I need to order replacement gaskets before I start this job? Want to make sure I have everything on hand before I tear into it. …more

How to Fix a Seized RV Side Mirror - Complete Repair Guide

Already picked up this 2002 Georgie Boy motorhome and I've never dealt with a seized side mirror adjustment mechanism before — the ball joint and set screws won't budge at all. I've been wrestling with this for weeks now and I'm getting nowhere!

Before I give up and start looking at replacements, is there any way to free up seized mirror adjustments? I'm also wondering about the electrical connections - if I do need to remove the mirror (it's held on with 3 screws), how do I safely disconnect those electric cables that run to the dash controls? I really don't want to damage the wiring harness on top of everything else. …more
Ford E450 RV Tire Cupping: Causes, Diagnosis & Complete Fix Guide

Ford E450 RV Tire Cupping: Causes, Diagnosis & Complete Fix Guide

Walked out to our 2017 Ford E450 Class C this morning and noticed dangerous washboard-like tire cupping on the front right - is this safe with grandkids aboard? Left side is starting to join the party too. Here's the weird part though - this beast still tracks straight as an arrow, no steering wheel shimmy, turns fine, and when I jack it up the tire doesn't wiggle around like a loose tooth.

I'm scratching my head because everything LOOKS fine. Suspension components seem solid, shocks aren't leaking like my wallet at RV parks. But could the shocks actually be shot at only 36,000 miles? And more importantly - if I just slap new tires on this thing without fixing the root cause, am I just going to end up with expensive cupped tires again? …more

RVLock Atlas Keyless Entry Installation Guide - Quick 15-Minute RV Door Fix

Between the metallic grinding when I turn the key and the ominous clicking from inside my 2016 Bounder's door mechanism, I'm ready to upgrade to an RVLock Atlas keyless system. It's specifically designed for RV doors and seems to be the only keyless lock that fits my model. The installation was incredibly quick - it took just ten minutes and required only a small Phillips screwdriver and a jeweller's screwdriver to press the reset button during programming. The Atlas comes with a QR code linking to a helpful how-to video. Just be aware it's a significant investment at $299. While pricey, the straightforward installation makes it appealing for a DIY RV owner. …more
Ford E450 V10 Spark Plug Replacement: Easy Access to Cylinders 1 & 2

Ford E450 V10 Spark Plug Replacement: Easy Access to Cylinders 1 & 2

The second my wife mentioned that my E450 V10's engine bay "looks like it was designed by someone who hates mechanics," I couldn't stop thinking about these impossible spark plugs. I need to change the spark plugs on cylinders 1 and 2, but it looks like Ford's engineers were having a laugh when they buried these babies behind what appears to be half the engine's wiring harness.

I'm hoping there's some secret RV mechanic wisdom out there before I start disconnecting every wire harness bracket in sight. Please tell me there's a way to get to these plugs without performing major surgery on my engine bay. My back is already protesting just thinking about the contortions required! …more

1991 Ford E350 Winnebago Battery Ground Wire Location: Complete Troubleshooting Guide

Wondering if anyone else has dealt with corroded battery cables on their Class A before — replaced them easily last time, but this 1991 Ford E350 Winnebago's ground wire location has me completely stumped. I've traced the ground cable to a tie strap on the fender, but that's obviously just a routing point, not the actual termination.

Where does the battery ground cable actually terminate on these E350 chassis? Need to find the real connection point so I can clean it properly and install the replacement cable with a solid ground connection. …more

Ford E-450 Front Suspension Quick Fix: Class C Motorhome Repair Guide for Winnebago Owners

Our Ford E-450's front suspension is making grinding noises when I turn - is this dangerous with kids in our Winnebago? My 2007 Winnebago Outlook 31' has been driving like absolute garbage and everyone keeps mentioning this "quick fix" for Ford E-450 chassis front suspension issues. I've been crawling under this thing for hours trying to figure out what I'm even looking at.

I keep hearing about track bars, radius arms, coil springs - but honestly, I can't tell which is which on my setup. The suspension doesn't look like the simple diagrams I've seen online. Can someone please break down exactly what components are involved in this quick fix for the E-450 chassis? I really need to know what I'm dealing with before I make this worse than it already is.

I'm willing to take photos and get help from other owners if needed, but first I need to understand what parts I should even be focusing on. This motorhome has been my home and I desperately need to get this sorted out! …more

DPF Failure Code: Repair Cost & DIY Options for RV Diesel

According to my diagnostic scan the DPF failure code shouldn't be appearing since regeneration happened just 500 miles ago on my 2022 Holiday Rambler Cummins B6.7. Local Freightliner service center is quoting $6,400 for complete DPF replacement at 38,000 miles.

Before proceeding with this expensive repair, I need to verify: Is this quote within normal range for dealer pricing? Should my 2022 engine still have emissions warranty coverage that would apply to DPF failure? Are there alternative repair options like professional cleaning that might resolve the issue without full replacement?

Looking for technical guidance on the most cost-effective approach to address this DPF failure code before committing to the quoted repair. …more

Where to Buy Onan Generator Rubber Isolator Mounts: Complete Sourcing

Got caught in all that rain last week and now my 2008 Jayco Melbourne 29D's Onan 4000 generator rubber isolator mount has completely split and separated. I've tried the usual RV parts sites, checked with local shops, and even called a few places - either they don't carry them or they're backordered for weeks.

I really need to get this fixed before my next camping trip. The generator is already pulled out so it's the perfect time to replace these mounts, but I just can't seem to locate the right parts anywhere. I'm willing to try generic mounts if I can figure out the right measurements, but I'd prefer OEM if possible.

Does anyone know reliable sources where I can actually find these isolator mounts? I'm running out of options here and getting pretty frustrated with the whole situation. …more

1990 Tioga E-350 Won't Start: Complete DIY Troubleshooting Guide

Turned the key in our "new" 1990 Fleetwood Tioga E-350 and my wife immediately said "that's not starting, honey" — now I'm completely stumped. The engine turns over like it wants to start but just won't fire up. I've already replaced the fuel pump inside the tank, but I'm wondering if another pump might need replacement. I don't want to just start throwing parts at it. What's the best systematic approach to figure out why my Tioga won't start? Are there common failure points I should check first on these older E-350 based motorhomes? …more

RV AC Unit Failed After 3 Years - Warranty Claims & Repair Guide

Got a dead front AC unit on my buddy's 2022 Holiday Rambler Endeavor at 2 AM — need this figured out before we hit the road tomorrow morning. We're talking a rig that's not even 3 years old yet! He's got two other roof units still working fine, but this one just gave up.

Is this typical for RV air conditioners? Seems crazy short for something that expensive. Should he be looking at warranty coverage or is he stuck buying a new unit? Any advice on how to handle this with the manufacturer or dealer would be awesome! …more
