Onan 5500 Generator Problems: Complete Repair Guide

Spent three hours testing my 2014 Hurricane's Onan 5500 gen getting 11.8 volts output when every manual says it should be 12+ volts! Here's the weird part - when I disconnect the remote harness, the generator fires right up and purrs like a kitten. But the second I plug that remote connection back in, boom - both the remote start light AND the generator start light come on, and then... nothing. Won't start at all.

The really bizarre symptom is this chattering from the fuel pump when the remote is connected. I can literally feel the fuel line jumping around when I put my hand on it. It's like the pump is having some kind of seizure or something!

I'm guessing this has to be some kind of electrical issue between the control board and the remote system, but I've never seen anything quite like this before. Anyone dealt with this specific combo of symptoms on an Onan 5500? Really hoping there's a known fix because pulling this thing out of the RV again would be a major pain! …more

How to Repair RV Roof Soft Spots: Fix Water-Damaged Wood Step-by-Step Guide

My RV roof has had this squishy soft spot right next to the roof vent ever since we got hammered by that nasty rainstorm last month. When I step on that area, it feels spongy and I can tell there's water damage underneath the rubber membrane.

I'm pretty sure water has been leaking through the vent area and rotting the plywood underneath, which seems to be about a hand-sized area. I want to cut the rubber membrane back, replace the damaged wood, and then reseal it properly.

Should I be worried about the structural integrity? What type of materials should I use for the replacement wood, and how do I properly reseal everything to prevent this from happening again? I'm thinking of folding back the rubber, replacing the damaged section of wood, and then resealing the membrane over the new wood. …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

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 12V Lights Dimming: Complete Troubleshooting Guide

My neighbor insists it's the converter, the RV dealer swears it's bad wiring, and every YouTube video claims it's a dying battery—but my 12V ceiling lights keep dimming! One evening they're blazing bright like a casino, the next morning they're giving off all the enthusiasm of a sleepy firefly.

I've already checked my batteries, and they seem to be charging fine and in good shape. The converter is still humming and its fan is running normally. I'm pretty sure this isn't some fancy mood lighting feature I accidentally activated (though knowing my tech skills, anything's possible). The dimming seems totally random - sometimes they're fine, sometimes they look like they're on their last legs.

I've got a basic multimeter that I pretend to know how to use, but I'm not sure where to even start poking around. As a bonus weirdness, some of my under-cabinet light switches and the wall switch for the ceiling lights are getting really hot. Anyone know what typically causes this whole disco light show situation with 12V lighting systems? …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

How to Fix RV Slideout Rubbing Against Exterior Wall - Complete Repair Guide

How to Fix RV Slideout Rubbing Against Exterior Wall - Complete Repair Guide

Finally figured out why my neighbor's slideout glides like butter while mine scrapes horribly against the exterior wall every time — what's their secret? My slideout has started rubbing against the exterior bathroom wall, and the coach is perfectly level.

The main thing I've noticed is that the gap at the bottom of the slide is much smaller now compared to the top - it used to be about 1½-2 inches at the bottom, but now it's barely anything. There's also about a ½ inch difference in height from one end of the slide to the other when I measure from the top.

I've independently jacked up both sides of the slide more than an inch each and checked the gap, but neither showed a difference. When I crawled underneath, I couldn't see where the slide might have moved laterally closer to the wall. The exterior stripes still line up. I also noticed the shower hasn't been used in 6 years or longer (I bought this coach used).

I'm wondering if this could be some kind of drooping issue? I've heard about things like rollers wearing out, but I honestly don't know what to look for or where to start troubleshooting. Should I be checking underneath the RV? Any advice on what might be causing this rubbing and smaller gap would be hugely appreciated! …more

RV Slide-Out Maintenance: Complete Guide to Prevent Wear and Extend Lifespan

Before I even finish extending my 2018 Newmar 2702 slide-out, there's this grinding vibration that kicks in during the final positioning phase every single time. The motor works hardest during that last foot of travel when the slide settles into place.

This observation has me questioning optimal maintenance protocols for slide-out longevity. What are the most effective strategies for reducing mechanical wear on these systems? I'm particularly interested in understanding proper usage frequency, seal maintenance requirements, and whether partial extension during routine tasks like cleaning provides any protective benefits.

Looking for comprehensive guidance on preventive maintenance practices, lubrication schedules, and storage considerations that will maximize slide-out system lifespan while minimizing premature component failure. …more
Fix RV Low Water Pressure on City Connection: Troubleshooting Pump Assembly

Fix RV Low Water Pressure on City Connection: Troubleshooting Pump Assembly

Last week my pressure regulator started reading a solid 40 PSI on city water but my water pump keeps cycling on for 5-6 seconds when everything says it should stay completely off. When I connect to city water, my water pressure regulator shows a solid 40 PSI, which should be plenty, right? But here's the weird part - my water pump keeps kicking on for about 5-6 seconds then shuts off, even though I'm connected to city water and the pump switch is supposed to be off.

The really frustrating thing is that the pressure feels weak throughout the RV, with specifically the bathroom sink and kitchen sink seeming low, though the shower has good pressure. I've already changed out the intake/check valve and don't currently have a filter in the system. I can see the pump running while on city water, which I know is not normal. I noticed the kitchen and bathroom sink screens were plugged - which might explain some pressure issues - but now I'm wondering about the toilet's low pressure. Could there be a screen in the toilet line I'm not seeing?

I've been full-timing for two years and never had this issue before. What should I be checking for? I'm handy enough to do basic repairs but need to know where to focus my troubleshooting efforts. …more

Fix Cracked Dometic RV AC Covers & Roof Vents

Already tried following a YouTube tutorial to fix the cracked Dometic air conditioner cover on my 2022 East to West 1900MMK travel trailer but somehow made the crack even worse. What are my repair options - can I fix the crack or should I replace the whole cover?

Also dealing with a broken cap on the roof tank vent. I'm curious about material choices - I've noticed galvanized steel can rust, while PVC seems to degrade in sunlight. What are the pros and cons of different vent cap materials? What's a reasonable price range for replacement?

How to Fix RV Fresh Water Tank Leaks: Complete Diagnosis & Repair Guide

Nobody warned me how tricky RV fresh water tank leaks could be — got my tools ready and determined to fix this dripping mess under my trailer myself. The dripping was pretty steady at first but seems to have slowed down overnight to just occasional drops. My tank gauge still shows full, so I don't think it's completely emptying out.

I can see there's an underbelly cover that would need to come down to access everything underneath, but I'm hoping maybe there are some easier spots I should check first? I'd rather not tackle removing panels if I don't have to - any guidance on where these leaks typically start would be really helpful, especially near the drain valve! …more

RV 12V Auto Reset Breaker Size Guide: 30A, 40A, 50A Selection

Opened up my RV this morning to prep for our two-week cross-country trip tomorrow and the electrical system keeps tripping the breaker every time I run basic appliances! My RV's entire 12V system just died completely - no lights, no water pump, nothing. I've checked everything I can think of and I'm pretty sure it's the auto reset breaker that's failed.

I have a WFCO converter/charger setup with dual 6V batteries, but I can't get underneath right now to read what's stamped on the current breaker. I need to order a replacement but I'm not sure what amperage to get. I keep seeing 30A, 40A, and 50A options online but I don't want to guess wrong and either undersize it or waste money.

What's the typical auto reset breaker size for this type of setup? Is there a standard that WFCO usually pairs with dual 6V battery systems? …more

RV Water Pump Runs But No Water? Troubleshooting Guide

Finally looking at my RV water pump right now and it's running constantly but there's absolutely zero water coming out of any faucets. However, when activating any fixture throughout the system, the water pump initiates and runs continuously without producing water flow at any outlet point.

All system components appear to be functioning mechanically - pump motor engages properly, electrical connections are secure, and there are no visible leaks in accessible plumbing runs. The symptom manifests uniformly across all water delivery points including kitchen, bathroom, and exterior service connections.

What diagnostic steps should be performed to identify the root cause of this no-flow condition despite continuous pump operation? …more
