Ideal V8 rpms when towing?
My F350 SRW 4x4 with 6.2L gas has a 3.73 axle and 18" tires. I carry a 9'6" NL truck camper which puts me at about 11,000lbs total. When cruising at 70mph, I turn 1,800rpms in 6th gear, and 2,300rp...

Torque, rpms, sweet spot... it all sounds great, right? Try this try towing your trailer over the same route at different speeds, and see how much your fuel mileage changes at the different speeds. Then pick the speed/fuel mileage you can live with. You'll be surprised how fast your fuel mileage drops the faster you go. When I was working, I was in a hurry, and towed at 75 mph and used to get 4.5 - 5.5 mpg. After I retired, I tried slowing down to 62-65 mpg and my fuel mileage climbed to 8.5 - 10 mpg. I guess I'm not in that much of a hurry any more.
