RV Sidewall Blistering & Delamination Repair Guide

According to three different RV shops, fixing my bubbling sidewall delamination will cost thousands, but I'm wondering if tackling this DIY repair myself is actually feasible. My 2004 Itasca Sunova has decided to sprout some lovely blisters on the right sidewall - two beauties that are about 12-14 inches long and 3-4 inches wide, running vertically right behind the awning arm. Perfect timing since we're currently on the road living our best RV life!

I'm pretty sure water snuck in somewhere (probably from the roof rail or that shower skylight we never use), and now my RV looks like it's got chicken pox. Since we can't exactly pull into the nearest RV surgeon's office, I need to know: what can I do right now to stop this from getting worse, and what's involved in actually fixing this mess properly? I'm hoping there's some kind of emergency containment plan that doesn't involve duct tape and prayers! …more

How to Replace RV Slide Topper Fabric: Complete DIY Guide

I pulled into three different campsites this month and my torn slide topper is eating through my gear faster than I can replace it. I've never done anything like this before and I'm worried I might damage the whole mechanism or make things worse.

Can I actually replace just the fabric portion safely, or should I bite the bullet and have the entire assembly replaced by a professional? I'm also concerned about costs - I'm hoping this won't break the bank. If it is something I can do myself, how difficult is it really? I don't want to get in over my head and end up with a bigger problem than I started with.

Can you help me understand the best approach for my specific situation? …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

RV Window Seal Leaking: Complete Repair Guide & Solutions

Opened up my RV window seals yesterday thinking I fixed the leak, but water's still dripping through during today's downpour — what did I miss? The rubber seals around the frames are obviously shot, all cracked and dried out looking.

I'm torn between two approaches here: should I take the time to completely remove the old seals and put in new butyl tape/rubber sealing, or can I just run some caulk over the existing stuff and call it good? Looking for the best long-term fix that'll actually keep me dry! …more

How to Replace Atwood Levelegs Control System with GAMA Electronics RF340-4PR Controller

How to Replace Atwood Levelegs Control System with GAMA Electronics RF340-4PR Controller

Noticed my Tiffin Allegro Bay's Atwood Levelegs control pad has a completely blank display, won't respond to any commands, AND all the leveling jacks are totally dead. I'm looking at expensive repair options - around $400 for repair service or $3000+ for a complete Bigfoot replacement system.

I researched alternatives and found the GAMA Electronics RF340-4PR-ASL controller with HP4PR-ASL handheld pendant, which cost around $235 shipped. I customized the solution by 3D printing a switch panel with 4 DPST on/off switches and a momentary DPDT switch for jack control.

Is this type of aftermarket replacement reliable and compatible with existing Atwood jacks and wiring? I want something I can easily troubleshoot and maintain. …more

Balance Beads with Internal TPMS Sensors - Real Experience

Since it's 2 AM and I need to hit the road at dawn, I'm desperately trying to figure out if balance beads will interfere with my RV's internal TPMS sensors. I keep reading about how great balance beads are for eliminating wheel vibration, but I'm terrified of damaging those expensive TPMS sensors inside the wheels.

What if the beads hit the sensors and break them? Or interfere with the signal? I can't afford to replace TPMS sensors if something goes wrong. Has anyone actually done this successfully, and are there special precautions I need to take with bead size or how they're installed? I need to know this is safe before I risk it. …more

Tiffin Allegro Bus vs Newmar: Complete Owner's Comparison Guide

Finally decided to stop watching YouTube comparisons between Tiffin Allegro Bus and Newmar coaches since every reviewer contradicts each other and I'm more confused than ever. I've been researching for months and keep going in circles. Currently own a 2019 Tiffin Allegro Bus 40ip and absolutely love it, but we're looking to upgrade to a 45-footer and suddenly questioning everything.

Everyone says both Tiffin and Newmar are top-tier quality, but I need to understand the real differences. What makes each brand stand out? Is Tiffin's customer service really that much better, or is it just hype? Are Newmar's interiors actually more luxurious, or is that just marketing?

I've read every forum post and review I can find, but I really need someone to break down the key differences so I can make a decision and move forward. We're not buying new, looking at newer used models, but this choice is keeping me up at night! …more

HWH 325 Levelers Shutting Off When Extended? Quick Fix Guide

This might sound like a warranty question, but before I start tearing into my HWH 325 series levelers that shut off when extended — they power up just fine - all lights, sounds normal, no drama. But the SECOND I press any of the extend buttons, they shut off completely like I just insulted their mother. I'm trying to level out while changing my motorhome's oil (because apparently I can't even do basic maintenance without my house deciding to be crooked), and these levelers are having none of it. Battery shows good on the panel, but I'm wondering if there's some kind of voltage issue happening when they try to actually work? Or maybe loose connections somewhere? Anyone dealt with this particular brand of RV stubbornness before? …more

4R100 Transmission Temperature Gauge Sender Location Guide for RV Owners & Mechanics

Despite my RV mechanic insisting I need a completely new 4R100 transmission for overheating, shouldn't I install a temperature gauge first to verify what's really going on? I can't seem to find any factory temperature sender on this transmission - am I missing something obvious?

I'm nervous about drilling into the pan or tapping into lines since I don't want to create leaks or cause more problems than I'm trying to solve. Is there a safe, proven way to monitor transmission temperature on a 4R100 without risking damage? I've heard about electronic options too but not sure if they're reliable. …more

Ford E-450 Class C Front Squeak: Brake Diagnosis

Between leaving my campsite last night and starting up this morning, my Ford E-450 Class C developed this awful front-end squeaking that definitely wasn't there before. My 2004 E-450 Class C with 54k miles has developed a squeak coming from the front end, and I'm not sure how to figure out what's causing it.

The squeak seems to happen at different times - sometimes when I'm braking, other times when going over bumps or rough roads. I've heard it could be anything from brake issues to suspension problems, but I honestly don't know how to tell the difference or what to check first.

Could someone help me understand how to properly diagnose where this front squeak is coming from? I'd really appreciate any step-by-step guidance on what to look for and how to identify whether it's a brake problem versus suspension issue. …more

How to Replace Your RV Door Awning Motor Cap: Step-by-Step Guide

I tried getting answers about my RV sideswipe damage but my insurance adjuster says it's totaled, three body shops say fixable, and forums are completely split. The coward took off at the highway exit before I could get his plates. Damage is to the bay doors and right front corner cap area - looks pretty ugly but the RV is still drivable. Police never showed up despite multiple calls over 4 hours of waiting. Already filed with insurance and sent photos, but I'm wondering what I should be looking for beyond the obvious visible damage. This is my first accident in 8 years of RVing and I'm stressed about hidden issues I might miss. Any advice on what to inspect or document before the adjuster comes out? …more

RV Red Warning Light: How to Identify Unknown Electrical Components

Woke up to find my RV's mystery electrical component glowing red instead of the green light the manual promised, and I can't even figure out what this thing is! In the picture I uploaded, you can see the component with the red warning light that just started appearing recently. I'm pretty sure that's not a good sign, right?

I'm thinking it might be some kind of detector or maybe part of the electrical system? There are so many gadgets crammed into these rigs. Anyone know what typically has red warning lights in RVs and what I should be looking for to figure out what this thing actually is? Would love to get it sorted before it becomes a bigger problem! …more
