Before every camping season rolls around, I face the same dreaded reality with my Ford V10 motorhome crawling up mountain passes like a wounded turtle. What are the realistic costs involved? Are there major risks to the engine I should know about? Is this actually worth doing or should I look at other options? …more

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?

Which of the 3 programs works best for RV towing? Is the investment worth it for better drivability or just hype? …more

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

This is the third time this season my '07 E450 motorhome's cruise control drops from overdrive straight to 3rd gear on hills and I'm done with this transmission madness. I just want it to stay put in Drive and stop being so jumpy.

I know newer trucks have those manual shift modes where you can lock a gear, but this old 5-speed auto doesn't have that luxury. Anyone know if there are aftermarket transmission controllers or mods that can hold it in Drive gear without all the hunting around? Would love to have more control over when it shifts. …more

During my search for a 2012 Fleetwood Bounder 35H and Thor Hurricane 35C with V10 engines, my existing UPFORD tune has become a confusing mess. My current Class C has an UPFORD Ultra tune that I installed about five years ago, and I've been extremely satisfied with the performance improvements - better gear holding, reduced downshifting from 5th to 4th to 3rd, lower RPMs, and significantly less engine noise.

UPFORD offers a transfer service where I can move my existing tune to the new motorhome for a fee, but I'm wondering if I should consider switching to a different tuning company instead. The main alternatives I'm looking at are Banks Power and 5 Star Tuning, since these seem to be the three most popular V10 performance tune options for RV applications.

From a cost-effectiveness standpoint, would it make more sense to transfer my current UPFORD tune to the new Class A, or are there compelling reasons to start fresh with Banks or 5 Star? I want to make sure I'm getting the best possible performance and value, especially since all three companies seemed to offer similar benefits when I originally researched this five years ago. …more

The mechanic wants to replace all my fuel injectors on my 1996 F53 460 motorhome after I installed a Banks Power system with Accel 24 lb, but this sounds like complete overkill. injectors. It's been running rough, especially at idle, and I'm getting intermittent check engine lights. I don't want to make things worse by guessing or doing the wrong repairs.

I'm honestly a bit intimidated by fuel system work - I've heard horror stories about people causing expensive damage. The injectors I installed were Accel 24 lb., and I want to confirm if these are correct for this engine. I'm planning to pull a plug soon to check my fuel mixture, but I need some expert advice on the safest way to diagnose whether my injectors are actually the problem. I want to be absolutely sure before I start throwing parts at it or risk damaging something else in the fuel system. …more
