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

Best Cummins 6.7 Scan Tools for RV Diesel Diagnosis & DPF Regen (2024

The internet seems to give me six different answers about which scan tool actually works with my 2019 Fleetwood's Cummins 6.7L—am I missing something obvious here? Need comprehensive coverage for reading and clearing fault codes, monitoring engine parameters, and performing forced DPF regeneration cycles.

Considering several options including the Foxwell HD500, Ancel heavy-duty scanners, and various BlueFire/Inline adapters available through different suppliers. Price ranges vary significantly from budget OBD2 adapters to professional-grade diagnostic equipment.

Looking for detailed comparison of available scan tools specifically for Cummins 6.7 applications - both professional-grade and DIY-friendly options.

Ford F53 Chassis Firewall Wiring: Finding Brake LED Through-Holes

Opened up my 2022 Holiday Rambler 36DB for spring prep and once again I'm staring at my 2021 Ford F53 chassis firewall wondering where those brake LED through-holes are hiding. I need to run the brake indicator LED wire from my toad to the dashboard inside the motorhome, but I'm having trouble locating the best firewall penetration point.

Rather than drilling a new hole through the firewall (which I'd prefer to avoid for obvious reasons), I'm hoping to find an existing through-hole or grommet that I can utilize. I've heard that Ford F53 chassis typically have several factory access points, but I'm not sure exactly where to look or which ones would be most suitable for this type of low-voltage wiring installation.

Can anyone provide specific guidance on where to find existing firewall through-holes on the F53 chassis that would work well for routing brake indicator wiring? I want to make sure I'm using an appropriate location that won't interfere with existing systems and will provide a clean, professional installation. …more

Ford F53 Godzilla V8 Suspension Problems: Fixes & Upgrades for Class A Motorhomes

Halfway through my first long trip, this bone-rattling vibration and unsettling sway started plaguing my newer Class A motorhome with the Ford F53 Godzilla V8 chassis. Coming from a 26' travel trailer and a history with brands like LazyDaze, I'm trying to understand the current RV landscape. I saw a Baystar 2023 model where the owner spent around $35,000 on suspension upgrades after just 12,000 miles.

Sounds awesome on paper, but I keep hearing people say you still need to dump a ton of money into suspension upgrades to make these things handle decently on the highway. Did Ford actually improve the suspension setup when they introduced the Godzilla engine, or are we dealing with the same basic chassis design that's been around forever? I'm talking about 30+ foot Class A rigs here - seems crazy that a $200k motorhome would need immediate aftermarket work to drive safely.

Anyone know if the Godzilla F53 combo actually fixed the handling problems or if it's just more power on the same wobbly platform? …more

Mercedes Sprinter RV Extended Warranty: Worth the Cost in 2024?

Walked into the dealership at closing time with my 2022 Thor Quantum MB24 and they're pressuring me to decide on extended warranty coverage before they open tomorrow. The original Mercedes chassis warranty has already expired since it was put in service in 2021, and the dealer is pushing a 4-year/60,000 mile extended warranty.

I keep hearing that Mercedes Sprinter repairs can be really expensive, but I honestly don't know what to expect or what questions I should even be asking about the warranty coverage. Are there specific things I should make sure are covered? What kind of repair costs are we actually talking about with these Sprinter RVs?

I'd really appreciate any guidance from folks who've been through this decision before. Thanks for helping a newbie out! …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 F53 460 EGR Valve Cleaning Guide - Fix Motorhome Stalling Issues Now

Despite probably being a dumb question, why does my 1997 Ford F53 with the 460ci keep being such a real pain lately? Keeps stalling out when I'm sitting at lights or just idling around. This happens every 400-600 miles like clockwork - runs great for a while, then boom, stalling starts up again.

I'm pretty sure it's the EGR valve getting all carboned up because I've seen this pattern before. The thing is, I'm getting tired of dealing with this over and over. Should I just clean the EGR valve again, or is there a better long-term fix? I've heard people talk about EGR deletes but not sure if that's the way to go with the ECU and all that. …more

2022 Ford E450 Check Engine Light: Complete DIY Troubleshooting Guide

Last week marked the third time this month my 2022 Ford E450 motorhome check engine light flicked on at only 4,000 miles and I'm done with mechanics. Last month I had the engine serviced at a local shop, and everything seemed fine when I drove it home. The RV ran perfectly for several weeks without any issues whatsoever.

Yesterday when I started the engine, the check engine light came on and stayed illuminated. According to my Ford owner's manual, this particular warning light is typically related to emissions system problems rather than more serious engine damage. The timing is suspicious given that it appeared shortly after the recent service work.

I don't currently have an OBD2 scanner to pull the specific diagnostic codes, and I'm really hoping to avoid another expensive trip back to the shop just to have them run basic diagnostics. Before I spend more money on professional diagnosis, are there any standard troubleshooting steps I can perform myself to potentially identify and fix simple issues that commonly cause check engine lights on these Ford E450 chassis? I'm particularly interested in emissions-related problems that might have been disturbed during routine service. …more

DPF Failure Code: Repair Cost & DIY Options for RV Diesel

According to my diagnostic scan the DPF failure code shouldn't be appearing since regeneration happened just 500 miles ago on my 2022 Holiday Rambler Cummins B6.7. Local Freightliner service center is quoting $6,400 for complete DPF replacement at 38,000 miles.

Before proceeding with this expensive repair, I need to verify: Is this quote within normal range for dealer pricing? Should my 2022 engine still have emissions warranty coverage that would apply to DPF failure? Are there alternative repair options like professional cleaning that might resolve the issue without full replacement?

Looking for technical guidance on the most cost-effective approach to address this DPF failure code before committing to the quoted repair. …more

Class A vs Super C Motorhome: Complete Comparison Guide 2024

Before I commit to my next RV purchase, I'm trying to decide between a Class A and Super C motorhome after our recent 2+ week, 3K mile trip through PA-OH-KY-NC-VA and back to CT. We have never seen more Super C's. They used to be a bit of a unicorn. This trip, multiples each day and a 1 or 2 at almost every campground.

A friend says it's the more dependable Freightliner drivetrain. If we were to make the swap from a 5th wheel (not likely), it would probably be a Super C. I'm trying to understand why the market seems to be shifting.

I'm looking to understand the technical advantages: Are Super C's really more reliable because of the commercial truck chassis? Is the Freightliner drivetrain genuinely better than traditional motorhome platforms?

Anyone care to share their opinions and experiences with Super C versus Class A motorhomes? …more

1995 Ford F53 460 Engine: Identifying EGR and PCV Valves | RV Repair Guide

Around 30 years into owning my 1995 Ford F53 with the 460 7.5L engine, I'm completely lost trying to locate the EGR and PCV valves. There are two valves that I can't identify - I'm pretty sure they're related to emissions control based on where they're located, but I'm not certain.

I think one might be an EGR valve and the other could be a PCV valve, but honestly I'm not confident in my identification. Should these valves be making any noise during normal operation? I want to make sure everything is working properly, but as someone newer to this, I'd really appreciate some guidance on what these components actually are and how they should behave. …more
