RV Electrical Problems: 12V & 120V Troubleshooting Guide 2024

Around $500 in parts later — replaced the main breaker, cleaned all connections, checked the transfer switch — my 2007 Holiday Rambler Admiral SE still won't recognize shore power.

I'm pretty sure 110V is making it to the rig since I can measure it, but somewhere between the plug and my appliances, something's not happy. Energy management panel is dark too. What's the logical troubleshooting order here? I keep hearing about transfer switches and breaker panels but honestly don't know where to start without making things worse! …more

1999 F53 V10 Oil in Coolant: Complete Head Gasket Diagnosis & Repair Guide

Called three dealerships about warranty coverage for oil contamination in my 1999 Ford F53 V10's coolant system — before I tackle this head gasket nightmare myself. The unit overheated after the oil level dropped significantly, though it still starts and runs without throwing any codes.

Based on the symptoms, I suspect a blown head gasket, but I want to perform proper diagnostic testing before committing to a major repair. What specific diagnostic procedures should I run to confirm whether this is actually a head gasket failure versus other potential causes like a cracked head or block issue?

Looking for a systematic approach to pinpoint the exact problem before I start tearing into this engine. …more

RV Rubber Roof Bubbling? How to Repair EPDM Separation

After 8 years of faithful service, my RV's EPDM rubber roof is starting to bubble with the membrane separating underneath — should I repair or replace? I'm concerned that if I don't address this soon, water could get in and cause major damage.

But I'm also nervous about trying to fix it myself. What if I make it worse by cutting into the roof or using the wrong products? Is this something that can actually be repaired, or am I looking at a full roof replacement? I'd really appreciate some guidance on whether this is a DIY-friendly repair and what the basic process involves. …more

RV Tire Age Limits: Why Replace Michelin Tires After 7 Years Despite Good Tread

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 Upgrade Your RV Converter Charger for Lithium Batteries with Gentle Care

Halfway through planning our three-week cross-country trip next month, I realized my PD4560 60-amp converter/charger won't properly handle the lithium batteries I'm installing. My existing Progressive Dynamics unit obviously isn't designed for LiFePO4 batteries - I can use boost mode to charge them up, but I know that's not ideal for battery longevity.

I just purchased a 30 amp generator and I'm wondering if it will have enough capacity to handle not just my current charger, but potentially a larger lithium-compatible unit. I'm considering upgrading to a 75 or even 90 amp charger to reduce charging times, but I need to make sure my generator can handle the load. I'm trying to figure out the actual AC amp draw of these higher-capacity chargers and whether my 30 amp generator will be sufficient.

What are the best lithium-compatible converter/charger options that would work with my generator setup, and how do I properly size the charger capacity to match my lithium battery bank? …more

RV Water Heater Not Hot Enough: Fix Lukewarm Water Issues

Looked forward to our two-week cross-country trip starting tomorrow until I discovered my RV water heater that used to produce scalding hot water now barely gets lukewarm. Both the electric and gas functions appear to be working - I can hear the gas igniting and see the electric indicator light - but the water temperature just won't get hot enough for a decent shower.

I've been dealing with this for weeks now and it's driving me crazy. The water gets warm, but nowhere near the hot temperatures I used to get. Is this a common problem with RV water heaters? What are the most likely culprits when you're getting lukewarm water instead of hot? I really need to figure out what's causing this and how to fix it before my next camping trip. …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

How to Fix Cracked Dometic RV AC Covers & Roof Vents: Complete Repair

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?

Looking for practical solutions for both issues. …more

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

Onan 4000 Generator Won't Start Without Choke: Code 14 Troubleshooting Guide

Halfway through another camping trip and trying to decide between babying my Onan 4000 with manual choke every startup or finally fixing this Code 14 nightmare. Let me try again:

Just found out that my 2013 Thor Class C's Onan 4000 generator won't cooperate after sitting since March, and I'm dealing with a nightmare. Been getting Code 14 errors and spent half the morning just trying to get it fired up.

The only way I can get it started is by manually messing with what I think is the choke linkage - otherwise it just won't go. Once I shut it off, same story - won't restart unless I physically manipulate that linkage again. Only has 240 hours on it and was serviced about 2 years ago.

I'm pretty sure the carburetor is gummed up from sitting, but what exactly does Code 14 mean? And more importantly, what do I need to clean to get that choke working automatically again? I really need to get this thing running properly before our next trip! …more

RV Whirlpool Refrigerator Cycling Every 30 Minutes: Is It Normal? [202

Looked everywhere for answers on my Whirlpool residential refrigerator cycling every 30 minutes—my neighbor says it's normal, RV dealer says it's broken, YouTube says something else entirely. The ambient temperature here is around 65°F, and I have both the fridge and freezer set to the 3rd snowflake setting.

I haven't timed it exactly with a stopwatch, but I keep noticing it kicking on again after what feels like a short time. I'm concerned this frequent cycling might be a sign of a problem or could lead to premature failure. I try to keep the vents clean when I can access them. Should I be worried about this 30-minute cycle pattern, or is this within normal range for an RV refrigerator in these conditions? …more
Onan 5500 Generator Tune-Up Guide: Best Aftermarket Parts & Filters 20

Onan 5500 Generator Tune-Up Guide: Best Aftermarket Parts & Filters 20

Before my last camping trip when I tried to order replacement parts, I discovered that finding genuine OEM components for my Onan 5500 generator has become nearly impossible. The Cummins website has been showing most tune-up components as out of stock for months now, and when I do find supposedly "official" Onan oil filters online, many retailers are substituting generic filters that may not meet the same specifications.

I've been researching alternatives and I'm particularly concerned about getting the right oil filter and spark plugs. For the oil filter, I've seen conflicting information about whether aftermarket options like Wix filters are truly compatible - some sources mention the 57398 but I've read mixed reviews about fitment issues. For spark plugs, my current ones are NGK BPR4EY, and I've heard the NGK 3432 might be equivalent, but I want to make sure before ordering.

I'm also planning to stick with zinc-containing oil like Rotella T6 15w40 since I know air-cooled engines need the extra protection, but I'd love confirmation that I'm on the right track with quality aftermarket parts that won't compromise my generator's performance. What specific part numbers and brands would you recommend for a reliable tune-up when OEM parts aren't available? …more
