All of the newer diesels are pretty tough & powerful & need no bullet proofing or aftermarket modifications to get the job done.
I am by no means advocating things like deleting the parts that cause the engine life to suffer a short existence, and get horrible fuel mileage, and reduce performance. BUT.... The things (government mandated) that are done to a modern diesel engine dramatically reduce it's life and performance. Raising the temperature to 1000° + to burn off soot in the DPF, and injecting Urea into the CAT, and recirculating exhaust (soot) back into the engine, AND having to cool that in a device the WILL eventually leak and destroy the engine. Not to mention a CP4.2 pump failure that will, well... ruin the engine as well. These are all cause for alarm, and anything that can be done to minimize these effects should be done. IMHO

Were talking about different rigs and bulletproofing etc, now so it’s gotten to far off topic. Letting it go to pasture.

I have my articles crossed on this and will find it.
Correct! I was wrong and you are right. The GMC/Chevy CP4.2 sucks gas out of the tank without a lift pump. However the CP4.2 has the other issue of not getting enough lubrication that eventually leads to its demise.

Thank you for correcting me!

Thanks fellas. I thought I was reading some diesel tech forum vs white knuckle sway with an RV as the OP started.....

Don't agree

I have a 2017 F 150 with the max tow package and a 2017 29 BHS. I have towed my TT up Berthoud Pass (elevation 11,000 feet +). I've driven it to Gettysburg from Colorado and am currently in the Black Hills in South Dakota. Never once have I felt unsafe. Just relax and take care to load your TT correctly and have fun.

Can I ask (and this might be slightly off topic) what the payload rating is on your setup? Be from the sticker on the door.

Oh, and my old 2001 Duramax didn't have a lift pump
