I read this topic and really feel the need to comment on my experience. I have a 99 F250 SRW 7.3 with 3.73 gears. I would really love to purchase a new truck but if I did that I wouldn't have an rv. I decided to upgrade my truck as it needed work anyway. I upgraded the suspension with 4400lb springs in the rear, bilstein shocks, upgraded brakes and tires. Transmission upgraded with converter and valve body. Engine upgraded with stage 2 injectors, HFSB Turbo, hp oil pump, 4"turboback exhaust, custom intake using BAAF filter, fuel line0 upgrades from Riff Raff diesel and Tuning from DP tuner. The truck runs phenomenal. Even with a modified stock tune. My 5th wheel is a 40' 13,330lb empty. I have towed it probably about 8000 miles now with absolutely no issues. I have several tunes that I use for towing mainly 20 and 40 hp tow. I can maintain any speed limit i have run into and routinely am passing big rigs going up the hills all with exhaust temps in spec. On the rare occasion I get caught behind someone and cannot accelerate early I may have to drop the trans out of OD. Last year I looked at new trucks again but after test driving them I was completely disappointed. They (all 3 brands) all seemed to lack the power of my truck. I am satisfied with what I have and to top it off I spent less that 10k for everything instead of 60k+.
