RV Inverter Guide: Modified vs Pure Sine Wave - Safe Power

My multimeter's out and I'm ready to tackle this RV electrical mess myself — pretty sure the inverter's the culprit but need to know where to start. I have a 2000 Winnebago Ultimate Advantage with four deep cycle house batteries and recently installed a Xantrex 758 inverter to replace my old Freedom 15 unit. The first time I tried using the inverter power while unplugged from shore power, something very strange happened - a hair dryer in the bathroom started running by itself and wouldn't shut off when I tried the switch. I had to unplug it, and the handle was warm. The hair dryer appears to be ruined now.

When I bought the Xantrex 758, I paid around $725 for what I thought was a good unit, but I'm now learning there's a difference between modified sine wave and pure sine wave inverters. I wasn't aware of this distinction when I made the purchase, and it turns out the 758 is a modified sine wave unit. I've since heard that modern electronics, especially things like residential refrigerators, computers, and sensitive electronic components, can be damaged by modified sine wave power.

I'm really concerned about potentially damaging my new residential refrigerator, stereo system, and computer equipment. Should I be worried about using this modified sine wave inverter with modern RV electronics? Is the hair dryer incident a sign that I need to upgrade to a pure sine wave unit, or are there other factors that could have caused this problem? I'm trying to understand if my current setup is putting my expensive electronics at risk. …more

Remote RV Diesel Fueling: Complete Guide for Campground Fuel Strategies

Last night at 11 PM I'm staring at my diesel RV's fuel gauge showing nearly empty — need to figure out remote campground fuel strategies before we head out this morning. With a 5 gallon Harbor Freight stick transfer pump, I've been able to add fuel when truck stops aren't convenient, but I'm concerned about static electricity risks.

My current setup involves using the pump to transfer diesel with the fuel can on a camping table, since my RV's fuel inlet is located under a slide. I pumped 10 gallons successfully, but I'm wondering about the safety of this method.

I know there are static electricity concerns when transferring fuel, and I'm curious about the specific risks with diesel. How safe is it to transfer fuel when the can isn't directly grounded to concrete? Are there best practices I should follow when manually adding diesel in remote locations? …more

Dometic RV AC Not Cooling? 5 Common Fixes for Air Conditioner Troubleshooting Guide

Walked out to my RV this morning trying to decide between calling a repair tech or troubleshooting my Dometic Brisk Air rooftop AC myself since it's showing weird operational issues. The compressor engages and fan motor operates normally, but the unit fails to produce cold air output. Temperature differential across the evaporator coil is minimal.

Unit functioned properly through previous cooling season with no apparent issues. Current symptoms include normal airflow volume but inadequate cooling capacity. What systematic diagnostic procedure should I follow to identify the root cause? Looking for a methodical troubleshooting sequence that addresses the most probable failure points in order of likelihood. …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

How to Fix RV Transfer Switch Not Detecting External Generator - Complete Troubleshooting Guide

The automatic transfer switch on my 1999 American Eagle detects shore power and onboard diesel genset fine, but won't recognize my external portable generator — can I fix this for under $50? The generator runs fine and produces power, but the transfer switch doesn't trigger to use it.

Atwood AFMD35 Furnace Playing Peek-a-Boo - How to Clean Flame Sensor & Fix Short Cycling

Staring at my Atwood AFMD35 manual that claims it should stay running once lit, but mine keeps shutting off every few minutes like it's playing peek-a-boo. It fires up beautifully for about 5-10 seconds, gets my hopes up that I won't freeze tonight, then promptly shuts off like it's having second thoughts about this whole "heating the RV" thing.

I've ruled out the sail switch and high temp limit since it actually lights (small victories in RV life, right?). I'm pretty sure the flame sensor is the culprit here, but I've never cleaned one before. How do I clean this mysterious little part, and what's the best way to access it on this model? Because apparently my furnace thinks playing hard-to-get is charming! …more

F53 Hydroboost Brake System Problems: Complete Repair & Troubleshooting Guide

Between the small hydraulic leak that started on my 1995 F53 hydroboost brake system last month and what's happening now, I'm wondering how much worse this nightmare can get. Right now it's just a slow drip - maybe one drop per minute - and I can feel the power steering is slightly stiffer than normal, plus the brake pedal requires a bit more effort than usual.

What I really need to understand is the theory behind how hydroboost systems operate, since this is different from the vacuum brake boosters I'm used to. More importantly, if this leak gets progressively worse and I don't address it immediately, what's my worst-case scenario? Will I completely lose power steering and power braking assistance, or would I still have manual control of both systems? I'm trying to figure out whether this is something I need to drop everything and fix right now, or if I have some time to plan the repair properly. …more

How to Fix Onan QD3200 Diesel Generator Fuel Leak Behind Air Filter

According to Murphy's Law, my Onan QD3200 generator is doing something bizarre — it's leaking diesel fuel from behind the air filter instead of where you'd normally expect fuel leaks. The fuel appears to be coming from somewhere behind the air filter box, and I'm worried about making things worse if I don't diagnose this properly. I've shut everything down for now because I'm nervous about safety issues.

I need to know the safest way to trace where this leak is actually coming from without creating a fire hazard or damaging anything. What are the most likely culprits in that area, and what's the proper procedure to identify the exact source? I want to make sure I approach this methodically rather than just poking around and potentially making the problem worse. …more

Ford F53 RV Fuel Pump Problems: Why They Fail & How to Fix Them Permanently

Got a neighbor with a 2007 Ford F53 motorhome that runs flawlessly while my 6.8L keeps burning through fuel pumps — what's his secret? The fuel pump has failed THREE times in just four years, and I'm scared there's something seriously wrong that's not being diagnosed properly. Each time the dealer just replaces the pump and says everything looks fine, but this can't be normal, right?

I'm starting to wonder if I'm doing something wrong with storage or if there's an electrical problem that's killing these pumps. The last thing I want is to get stranded somewhere dangerous because of another failure. Should I be worried about contaminated fuel? Could my storage practices be causing this? I really need to understand what's actually causing these repeated failures before I spend more money just replacing pumps that are going to fail again. …more

1988 Fleetwood Tioga Ford E350 Ignition Relay Location Guide

Last weekend I bought my first RV, a '88 Fleetwood Tioga Arrow (Ford E350 chassis, 460 V8), and I'm completely clueless why it won't start. I've already swapped out the starter solenoid on the fender, but now I'm being told there's also an ignition relay that could be the culprit.

Problem is, I can't for the life of me find this thing! I've been crawling around the engine bay for what feels like hours. Anyone know the typical spots where Ford hid the ignition relay on these E350s? Really don't want to start randomly pulling relays until I find the right one... …more

Coleman Mach AC Leaking Water Inside RV: Complete Troubleshooting Guide to Stop Drips

I'm planning my weekend getaway when I spotted water dripping from my Coleman Mach air conditioner model 49003A879 that definitely wasn't there yesterday. I'm in Myrtle Beach, with super humid conditions (90s with crazy humidity) and getting pea-sized water drops falling from the ceiling vents at maybe 2 drops per minute, which doesn't sound like much but it's making puddles on my floor.

I've been keeping the main ceiling vents mostly closed to push more air to the back of the coach. Climbed up on the roof expecting to find some fancy drain pump or tubing system, but honestly don't see much of anything obvious.

Is this just how these Coleman units work, or am I missing something? Really hoping this isn't a 'deal with it' situation, but wondering if my closed vents are screwing up the airflow or if there's actually a drainage problem I need to fix. …more

1999 Pace Arrow F53 Fuel Pump Replacement - Expert Advice

According to my troubleshooting so far, I've replaced the fuel filter, cleaned the fuel lines, checked all the connections, and even swapped relays — but my 1999 Pace Arrow F53 still won't get fuel to the engine. The original fuel pump has been operational for 27 years, exposed to gasoline storage conditions throughout this period.

Given the extended service life and potential for roadside failure, I'm evaluating whether proactive fuel pump replacement represents sound maintenance strategy. Seeking technical assessment on replacement timing and expected performance outcomes with quality aftermarket units from established suppliers.

What are the documented results from similar preventive fuel pump replacements on this chassis configuration? Is the investment in preemptive replacement justified based on reliability data? …more

How to Fix Onan Generator That Won't Stay Running After Running Out of Gas

Halfway through our camping trip, my Onan 4KY-26100R generator on a 2018 Winnebago Spirit is doing something bizarre — firing up perfectly after running out of gas but dying within minutes. After refilling the tank and changing the oil, the generator starts but immediately shuts off when I release the start switch. Getting 3 flashes on the control switch indicating service required. Oil level is correct - halfway between add and full marks. Is this an air in fuel system issue from running out of gas? How long should I hold the start switch to get it running again? …more

F-53 Motorhome Leaf Springs: Complete Replacement Guide & Warning Signs to Watch

My F-53 motorhome still bounces like a trampoline over every bump despite replacing the shocks, checking alignment, and rebalancing the tires. I have a 1995 F-53 motorhome that's been in Arizona its whole life, so thankfully no rust issues.

I keep seeing posts about people replacing leaf springs on much newer rigs, and it's got me wondering if I should be doing the same. My coach is 30 years old now, but honestly I don't see any obvious sagging and the springs look okay to my untrained eye. I do have some worn bushings that I'm planning to replace.

What are the actual warning signs that leaf springs need to be completely replaced? Am I missing something obvious, or could my old Arizona springs actually still be fine? I don't want to spend money I don't need to, but I also don't want to ignore something important for safety. …more

Ford Triton V10 RV AC Repair Cost: Is $1400 Fair for Evaporator Replacement?

Already standing in the RV service bay staring at a $1400 evaporator replacement quote for my 2002 Pace Arrow with Triton V10 with no clue if that's highway robbery or fair. Tech says evaporator, dryer, and expansion valve all need replacing. Quoted $1400 for parts and labor, says it's an 8-hour job because of dash removal.

Is this price reasonable for this type of repair? What should I expect to pay for parts vs labor on a dash-intensive AC job like this? …more
