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 Battery Draining Overnight? Find & Fix Parasitic Drain

The day after I installed that new solar charge controller last month, my RV batteries started mysteriously draining from fully charged to completely dead overnight. I've already confirmed that all visible lights, fans, and appliances are turned off, and I've switched off the main interior power, but something is still drawing power continuously. I understand this is likely a parasitic drain where some component or circuit is staying energized when it shouldn't be, but I'm not sure how to systematically track down which specific circuit is causing the problem. I have a basic multimeter but I'm not entirely sure about the proper methodology for testing each circuit individually to isolate where exactly the power draw is coming from. What's the step-by-step process for using a multimeter to methodically work through the electrical system, starting from the main disconnect and testing individual fuses or circuits until I can pinpoint the exact source of this parasitic drain? …more

Onan 4000 Generator Surging: Step-by-Step Fix Guide (2024)

Despite my neighbor's Onan 4000 generator purring like a kitten, mine suddenly developed nasty surging issues yesterday — what's going wrong? It surges when cold, then settles down as it warms up. Under load it surges heavily until the appliance shuts off. Getting worse each day.

What are the main causes of generator surging? Need a step-by-step approach to diagnose and fix this - should I start with the carburetor, fuel system, or something else? …more

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

Fleetwood Discovery Generator Won't Start: Battery & Electrical Fixes Guide

Since the manual says to check the fuel shutoff solenoid first on my 1999 Fleetwood Discovery 37V diesel pusher generator, why am I getting power there while the battery connections are completely corroded? The generator absolutely refuses to start unless I run the main Cummins engine for several minutes first, and I've already tried using the boost battery switch which seems to do nothing.

I have brand new batteries - two 12V for the chassis and four 6V house batteries properly wired. Everything else works fine, but this generator issue has me concerned. I want to understand: 1) Why won't the gen set start from its batteries without the main engine running first? 2) Which battery bank does the gen set actually use - chassis, house, or a separate gen set battery?

I'm 80 years old and hesitant to crawl under the coach to trace the gen set 12-volt cable. Can someone help me understand what might be happening with my generator's electrical system? …more

RV Electric Leveling Jacks Won't Extend - Fix Clicking Issue

Wondering if I should drop $800 on new electric leveling jacks or if this annoying clicking issue can actually be fixed first? The jacks were working perfectly fine on our last camping trip about two weeks ago, but now when I try to extend them, I can hear a distinct clicking sound coming from the controller panel, yet none of the jacks actually move or extend. The clicking happens consistently when I press the extend button, so it seems like the system is trying to respond, but something is preventing the actual mechanical operation.

I'm wondering what the most common causes are for this specific symptom - where you get the clicking from the controller but no actual jack movement. I'd like to understand the logical troubleshooting sequence, starting with the easiest things to check first before I dive into more complex diagnostics. The RV has been sitting plugged into shore power, but I know these systems can have multiple potential failure points including electrical, hydraulic, or control issues.

What should I be checking first, and what's the typical progression for diagnosing electric leveling jack problems that manifest with clicking sounds but no extension? …more

Onan Generator Fault Codes: Complete Troubleshooting Guide for RV Owners

During my latest camping trip my Onan generator threw a fault code — got my multimeter ready and just need to figure out which diagnostic approach will crack this thing.

I'm seeing 12 or 13 blinks on my generator error display and want to understand what these codes might mean. Are these codes consistent across different Onan models? I'm hoping it's a minor issue and not something requiring a major repair.

Can anyone help me decode what these blinking fault codes typically indicate? …more
Motorhome vs Toy Hauler Electrical Systems: Complete Comparison Guide

Motorhome vs Toy Hauler Electrical Systems: Complete Comparison Guide

Walked into three dealerships with my $40k budget and they're all pushing different electrical setups — can't afford to buy wrong between motorhome vs toy hauler power systems. Currently I have a 2020 F350 diesel SRW with a Reflection 29rs toy hauler, and I'm comparing a Grand Design Lineage 31ZW Super C motorhome versus a Momentum 381MS toy hauler.

The toy hauler I'm considering comes with serious electrical upgrades - 2 heated 400Ah lithium batteries with internal BMS, dual 3,000kVA inverters, four 300W bifacial solar panels, dual 50A solar controllers, and 60A DC-DC truck charging. Currently, to transport my side-by-side (SxS), I need two trucks and two trailers, which is inefficient.

I'm weighing pros and cons like overall length (truck and toy hauler would be about 60', MH and 20' cargo trailer would be about 57'), maintenance costs of keeping two diesel trucks, and transportation flexibility. I also have an F150 that could potentially serve as a toad vehicle.

What experiences can others share about transitioning between these RV types, especially considering power management and transportation logistics? …more

Stop RV Battery Drain During Storage - Expert Solutions

Planning to store my 2012 Winnebago Tour and there's clear signs of battery drain happening across all six house batteries and two chassis batteries. I'm religious about flipping both the chassis and house disconnect switches before putting her away for storage. Still go out monthly to fire up the generator and top off the batteries.

But here's the thing that's driving me nuts - even with those disconnect switches flipped, my batteries are still going dead! Sometimes I can't even get the engine started and have to hook up a trickle charger just to get things going again. What's the deal? I thought those disconnect switches were supposed to prevent this whole mess. Am I missing something obvious here, or is there more going on that I need to tackle? …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

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

Ford F53 Chassis Misfire Problems: Early Spark Plug & Coil Failure Solutions

Walked out to my 2021 Class A motorhome this morning facing the third Ford F53 chassis misfire this year and I'm done throwing parts at it blindly. We've got less than 20,000 miles on the odometer, but recently experienced rough running and got a check engine light. When I took it to a Ford dealer that services Class A rigs, they diagnosed misfires in two cylinders and recommended servicing the entire fuel system. I ended up having them replace all eight spark plugs, plug wires, and ignition coils since we were already dealing with failures.

The coach now runs better than it ever has since new, which makes me think the original components may have been subpar from the factory. What's really bothering me is that we shouldn't need major ignition system work this early in the vehicle's life. I'm curious if other owners of 2021 or newer F53 chassis motorhomes have experienced similar premature failures with their spark plugs, ignition coils, and plug wires? Is this pointing to some kind of quality control issue with Ford's ignition components on these newer chassis, and should I expect better reliability from aftermarket replacements going forward? …more

Why Your RV Generac Diesel Generator Shuts Off After 2 Minutes Under Load: Troubleshooting Guide

Found that ever since those heavy rains last month hit, my 2007 Alfa's Generac 7.5kw diesel generator shuts down exactly 2 minutes after firing up the basement AC.

Just did a full service (oil, filters, the works) so it's not basic maintenance stuff. I can restart it right after it shuts off, but if the AC is still calling for power, it dies immediately again. No error codes or blinking lights to give me a clue.

Is this a fuel delivery issue where it can't keep up with the AC load? Or am I looking at something else entirely? Really hoping someone's dealt with this exact same 2-minute thing before! …more

AGS Starting RV Generator with AC Load: Modern Systems vs Old Rules

I noticed I'm getting wildly different advice about whether my AGS should start the generator when AC kicks on—some say it'll fry contacts, others say it's fine?

I'm wondering if modern AGS systems have addressed these older concerns about generator startup under load. Is starting the generator directly through AGS when the AC demands cooling safe for the system? Would it be better to manually start the generator before leaving to allow a warm-up period, or is the current automatic load engagement fine with contemporary RV generator technology? …more
