Towing Question F-150 + Gulfstream Ameri-Lite 198BH

Ummm, yeah. Expect higher RPMs in the hills.

What engine in the truck?

Engine doesn't matter really in this case..he said max tow 5400, so he's got plenty of truck.. so it's obvious the small engine, but won't likely matter.

Not that it was right, but i towed a tt that was 3200 loaded with a 3500 max tow vehicle...I think you will do just fine.

That’s only a 3700# unit, you should do fine. Higher rpm on the hills, as said. Just don’t stop on any mountain grades. I came around a curve once and almost ran over some clown in a MH literally crawling up a 2 lane mountain road. I had to slam on my brakes and stop and I really thought I’d blow my transmission starting again. I was pulling a 3000# TT with a 302 Bronco and otherwise I was totally satisfied with it pulling the Rockies.
