Ford V10 Triton Engine Maintenance Guide: EGR Delete vs Regular Service Tips

Spent years doing regular EGR maintenance on my old gas motorhome without issues — but this 2007 Fleetwood 31' Tioga with Ford V10 Triton has me second-guessing everything. I keep reading conflicting information about EGR delete procedures on V10 engines, and I'm worried I might make things worse if I mess with it.

Is the EGR delete modification actually necessary on this 2007 3-valve V10, or am I overthinking this? I don't want to void any warranties or create problems that weren't there before. Would I be better off just sticking to regular maintenance instead of modifications? I'm looking for reassurance that I'm taking the right approach to keep this engine running reliably for years to come. …more

Ford E450 V10 Reliability: Expected Mileage and Longevity Guide for RV Owners

Nobody prepared me for staring at this 2018 Jayco Greyhawk 29MVP with Ford E450 chassis showing 54,000 miles and wondering if I'm looking at a money pit. The unit appears well-maintained with quality features including auto-leveling, fiberglass roof and nose, plus J-ride suspension. However, the odometer shows 54,000 miles, which exceeds my initial target range.

I need to assess whether this mileage represents significant wear on the E450/V10 drivetrain combination. What is the typical service life expectation for these engines when properly maintained? At what point should mileage become a primary concern versus overall mechanical condition? …more

Ford V-10 Misfire Codes P0305 & P0307: Complete RV Engine Repair Guide for Motorhomes

Turned my compression tester on cylinders 5 and 7 and got 150 PSI readings, but I'm still pulling P0305 and P0307 misfire codes on my 2001 Ford E350 V-10. The engine runs smoothly overall, but the diagnostic codes are persistent.

I have replacement spark plugs and ignition coils available but want to ensure I'm following the proper troubleshooting sequence before investing time and effort. What is the recommended diagnostic approach for simultaneous misfires on cylinders 5 and 7?

Given that multiple cylinders are affected, should I prioritize certain components over others, or is there a systematic order that typically yields the most efficient resolution for this engine configuration? …more

HWH 625S Slide Out Not Working: Step-by-Step Control Box Bypass & Repair Guide

Wondering why my 2008 Winnebago Adventurer 38J's HWH 625S slide out won't budge after replacing the solenoid, cleaning connections, and checking fluid levels? The passenger slide won't extend or retract from the wall switch, but when I manually operate the solenoid valves, the slide moves perfectly in both directions.

I've already replaced the solenoid valves, so I know they're good. The problem seems to be that power isn't reaching the solenoids from the switch - everything routes through the control box first.

Can I safely bypass the HWH control box by connecting the switch wires directly to the solenoid wires? What should I check before attempting this bypass? …more

Ford E450 V10 Spark Plug & Coil Replacement Guide - RV Engine Maintenance Tips

After handling coil swaps on my old Chevy like they were nothing, this Ford E450 V10 setup has me completely intimidated and second-guessing everything. I've heard cylinder #3 is particularly difficult to access and I'm scared I might break something or use the wrong tools.

I tried using a 7mm wrench like some sources suggested, but it doesn't seem to fit properly and I'm afraid of stripping the bolt heads. I'm also concerned about how to safely reach the coils without damaging other components.

Can someone please walk me through the safest approach and tell me exactly what size wrench I should be using? I'd rather ask for help than risk making an expensive mistake. …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

Ford V10 Multiple Coil Codes Driver Side: Diagnosis & Repair Guide

Somewhere under the hood of my 1999 motorhome's Ford V10 there's a complete light show of coil codes P0351, P0353, P0355, P0357, and P0359 blinking across the entire driver side bank. Power and ground tests at individual coils show normal readings, and visual PCM inspection reveals no obvious damage.

Given that all affected coils are on the same bank, I suspect this isn't a coincidence of multiple simultaneous coil failures. What are the most likely common failure points that would cause multiple coil codes specifically on one engine bank? Should I be focusing on shared wiring harnesses, common ground points, or PCM driver circuits before replacing individual components? …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.

2001 Ford F53 Firewall Module Identification: GEM, ICM & Fuel Pump Driver Guide

According to my spring ritual of firing up my 2001 Ford F53 for camping season, that same firewall electrical module overheats until the black plastic housing cracks. Looks pretty well cooked!

The part number isn't readable anymore thanks to the heat damage, and my local Ford parts counter is stumped. It's definitely some kind of power module since it has that chunky heat sink attached. Anyone know what the common firewall modules are on these F53s? I'm thinking it might be something like a GEM or ignition module, but honestly not sure what I'm looking at here. …more

Onan Generator Won't Stay Running: Complete Repair vs Replace Guide 20

Three distinct sputtering sounds keep coming from my Onan generator that fires up perfectly but dies out after running for a while. Multiple service calls and repairs have been attempted, but the problems persist intermittently, making diagnosis challenging.

The repair costs are accumulating significantly, and I'm reaching a decision point regarding whether to continue troubleshooting or consider replacement options. What criteria should I use to determine when total repair investment justifies switching to a replacement unit? Are refurbished Onan generators a viable alternative, and what factors should guide this repair-versus-replace analysis for intermittent generator failures?

(Note: This is specifically about my RV's Onan generator, which I'm referring to as my 'Jenny'.) …more

Ford F53 Motorhome PCM Failure: Complete Diagnosis and Repair Guide

Replaced the PCM on my 1999 Holiday Rambler Ford F53 chassis but still getting complete power loss with coil malfunction codes hitting an entire engine bank. That seems weird, right? Like what are the odds ALL the coils on one side would go bad at once?

I finally wrestled the PCM out (what a pain!) and found some discoloration on one side of the circuit board. Been reading online and seeing mixed info - some say it's the ignition system, others pointing to PCM failure. Really hoping it's not the PCM since those aren't cheap, but the whole bank thing has me wondering. Is this actually pointing to the computer being fried rather than ignition problems? …more

RV Heat Pump Amp Draw: How Many Amps Does Your Unit Use?

Turned down a Class A with a heat pump because I'm terrified of being that neighbor constantly tripping breakers — am I overthinking this? We're plugged into 30-amp service at home while I pretend to know what I'm doing with all these fancy RV features.

Basically, I need to know how many amps this heat pump is going to suck down when it kicks on. I'm already running the usual suspects - fridge, lights, maybe the TV so I can ignore my responsibilities - and I'd rather not find out the hard way that I'm overloading everything. Anyone know the typical amp draw so I can at least look semi-competent when explaining to my spouse why the power keeps cutting out? …more

Ford 6.8 V10 Spark Plug Change: Why 30K Miles Prevents Stuck Plugs in

Ford 6.8 V10 Spark Plug Change: Why 30K Miles Prevents Stuck Plugs in

Wondering if my extended warranty would cover spark plug replacement on our 2003 Ford 6.8 V10 at 30,000 miles before I start tearing into this job myself? We purchased this RV used at 25,000 miles, and I'm confident it still has the original factory spark plugs installed. I know these engines are notorious for spark plugs getting stuck in the cylinder heads if you wait too long to change them, but I'm trying to figure out the optimal timing.

I have experience with a similar situation on my 2006 4.6 V8 Ford engine - when I had the plugs changed around 25,000 miles, two of them broke off during removal and required special extraction tools at the dealership. That experience has me concerned about whether 30K miles is already too late for the V10, or if waiting longer would actually make the stuck plug problem worse.

What's the best approach for timing this maintenance on the 6.8 V10? Should I tackle this now at 30K miles, or is there a benefit to waiting longer? I'm also wondering about proper removal techniques and precautions to minimize the risk of broken plugs during the change. …more

1999 Itasca Sunflyer V10 Drivers Side Coil Bank PCM Issue

Pulled every trick in the book — replaced all five driver side ignition coils, swapped the PCM, checked every connection — my 1999 Itasca Sunflyer V10 still throws codes P0356, P0357, P0358, P0359, P0360. Running on 5 cylinders only.

Tested +12v at each coil connector - all good. Tested for ground pulse during cranking - nothing on drivers side, but passenger side coils pulse normally. No visible wiring damage found.

Does this testing confirm PCM failure in the ground switching circuit? Seems unlikely all 5 coils failed simultaneously. …more
