Ford E-350 vs E-450 Chassis: RV Fuel Economy, Power & Weight Capacity

Last weekend I felt this awful engine strain and heard sluggish acceleration sounds while test-driving a 2017 Phoenix Cruiser #2351 with its E-350 chassis and V10 engine. I'll be doing extensive western touring through mountain and plains regions, which means substantial mountain grades and wind challenges. I'm comfortable driving slowly and want to understand two key things: 1) Will this E-350 chassis handle mountain grades without major issues, and 2) What's the real-world fuel consumption like? I plan to do an initial inspection this weekend, followed by a third-party mechanical review. I'm not overly concerned about fuel economy but want to understand the actual performance limitations. I'd appreciate insights from owners who have experience with similar touring conditions on an E-350 chassis. …more

RV Shore Power Not Working: Complete Troubleshooting Guide

Plugged into shore power at the campground last night and absolutely nothing happened — no lights, no AC, nothing. Breaker on the pedestal looks fine and my neighbor's rig is running perfectly on the same circuit. Starting to wonder if something fried inside the transfer switch. …more

5 Star Tuner X4 for Ford V10 RV: Complete Performance & Upgrade Guide

Planning to tune my 2018 Ford 6.8L V10 RV but got quoted $800 for professional tuning and wondering if the 5 Star X4 is DIY-friendly. Specifically want to know about real-world performance improvements - does it actually improve throttle response and shift points? What about fuel economy gains?

1993 American Eagle Onan Generator Low Voltage Fix: Rectifier Bridge Corrective Steps

Tried everything to fix my 1993 American Eagle's Onan generator low voltage issue — about to buy a $150 rectifier bridge but is it actually the solution? Everything seems to run fine - it starts up without issues and sounds normal - but I'm only getting 12-15 volts output instead of the proper voltage I should be seeing.

I've been doing some research and think it might be related to the rectifier bridge or suppressor components, but I'm not entirely sure. The service manual mentions parts CR21 and RV21, but I'm honestly a bit overwhelmed trying to figure out exactly which replacement parts I need.

Could someone help me understand what's likely causing this low voltage issue and point me toward the correct replacement parts? I'd really appreciate any guidance from those more experienced with Onan generator repairs. …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

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

Norcold N7LX.3F Running Too Often: Complete Troubleshooting & Repair Guide

Standing in the RV supply store staring at replacement thermostats and control boards with no clue which one will actually stop my Norcold N7LX.3F from running constantly. It's been running way more frequently than it ever has before, and I can't figure out what's wrong. The cooling seems off too - items aren't staying as cold as they should be.

I've already checked the obvious stuff like making sure the vents aren't blocked and the unit is level, but something is definitely not right. The fridge just keeps cycling on and off constantly, which has me worried about both the power consumption and whether there's a bigger problem developing.

What should I be looking at to diagnose cooling efficiency issues? I really need to get this sorted before our next camping trip! …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

RV Hot Water Pressure Problems: How to Fix a Stuck Backflow Preventer in Your Water System

About four years into owning my 2019 Winnebago, the hot water pressure is starting to completely tank — should I repair this backflow preventer or replace the whole unit? My 2002 Winnebago with an Atwood 10 gallon water heater just lost all hot water pressure overnight. Cold water works perfectly fine, but turn that handle to hot and... nothing. Zero pressure at any faucet.

The weird thing is the tank itself has hot water and pressure - I can open the relief valve and water shoots out fine with good pressure. It's like something is blocking the hot water from getting out of the tank to the faucets. I've checked what I can reach and don't see any obvious blockages in the lines.

Anyone know what could cause hot water pressure to just disappear like this while cold water works normally? There's gotta be something simple I'm missing here. …more

Dometic RV Fridge Replacement: Residential vs RV-Specific Options Guide for Smart RVers

Replaced my old Dometic RV fridge but now I'm second-guessing whether I should have gone with a residential unit instead of another 12 cu. ft. residential unit - looking at Frigidaire or Whirlpool models. But I keep seeing terrible reviews for small residential fridges in RVs.

What causes these issues with residential fridges in RV applications? Are there better alternatives that give me residential-style features without the problems? Need to know about power requirements and installation considerations too. …more

RV Engine Stalling & Transmission Issues - Diagnosis Help

Replaced multiple parts but I'm still standing in the auto parts store aisle staring at diagnostic tools with no clue which one I actually need for my RV's stalling and transmission issues. When I'm cruising and let off the gas, sometimes the RPMs drop like a rock, other times they just hang there until I slow down more. That's weird enough, but here's the real kicker - every now and then the whole engine just dies on me when I'm rolling up to a stop sign or red light. Maybe happens twice in 600 miles or so, so it's not constant but definitely not normal either.

I'm wondering if these two issues are connected somehow? Like could whatever's causing the stalling also be messing with how the transmission acts when I let off the throttle? Really hoping someone has seen this combo before because I'm in Germany and finding RV-specific help is tough.

I'm looking for any insights from folks who might know what could cause this - hoping to get to the bottom of this before it becomes a bigger problem! …more

Staring at my 2007 Norcold N611's flashing NO CO lights shutting everything down — is there a DIY fix under $50 since I can't swing a $300 service call? The fridge loses cooling and then locks out completely. I can reset it and it works for a few days or weeks, then the same cycle repeats.

What exactly does the NO CO error code mean and what causes it? Need to understand what's happening before I start throwing more parts at this problem. …more

Advent RV Air Conditioner Not Cooling? Complete KoolRV Adapter Fix Guide

Advent RV Air Conditioner Not Cooling? Complete KoolRV Adapter Fix Guide

Around 6 AM I walked out to my fifth wheel and spotted my Advent air conditioner running but barely pushing any cool air through the vents. I replaced my old Coleman AC with an Advent, mainly due to price, but I'm not getting good cooling during the heat of the day. I've found that opening the slide vents on the ceiling cover helps a bit.

I'm considering using a KoolRV adapter like I had with my previous Coleman, but no adapter currently exists for the Advent. I've noticed the cold air discharge opening is located in the corner instead of the center, which I think is causing air turbulence and restricting duct airflow.

My main concern is whether restricting the airflow too much could cause problems like freezing up or other damage to the AC system. I've also seen that installing these adapters involves removing some kind of dividing wall inside the unit, but I don't understand why that's necessary.

Could someone explain if there are risks to restricting airflow and why that dividing wall needs to be removed? I want to make sure I understand what I'm getting into before I try any modifications. Right now, it's starting to cool down here in the Everglades, but I still want to improve my cooling performance. Thanks for any guidance! …more
