While I agree that the OP has more trailer than truck. I don't believe any of the statements about not feeling the big trucks pass just because you have a 250, or 350. The big trucks, and busses feel each other pass. You get the same push pull with them as you do with a TT, or 5er.
And as for those that say. They wouldn't tow any thing with a 1500, or F150. Maybe y'all shouldn't be driving. :B:B for I can honestly say. My F150 tows stops, and handles my 30' 6000lb TT better than our CLT9000 Road tractor handled, and stopped the 47' 50'000lb trailers it towed. BTW. the Big CLT9000 weighed 30,000lb
AND. Just think. If a 250 does better than a 150, A Mack will do better than a 250. You may as well go ahead and get a big truck, (road tractor) and quit playing with the little trucks.
