The F150HD would work well. THe 1500 GM with 1800 lbs of payload should work.
One has to remember, from a speed standpoint, less hp is slower. Smaller engine will make it so you go slower. For some an issue. other not.
WInd resistance on the trailer is also an issue, but not talked about.
So you live in an area with steeper grades? if so, then you want a combo of high torque, lowest gears possible in both the trans and rear end. An older 25 series truck with a 4.10 rear end, while supposidly a great ra for towing, it it is setup with a 2.48 first gear, you have all of about 9-1 overall low ratio. Mean while, a 3.42 geared rig with a 6.7 like the muncie 4 sp, has over a 20-1 overall low ratio. The 3.42 geared rig will pull a steeper grade assuming the same motor and truck than the higher rated 4.10 geared rig!
A new rig with 3.42 gears and the 6 sp from GM would work well. 3.73 a better option. I would personally want around 2000 lbs of payload. but 1600-1800 would work. That is upwards of 1200 for hweight, 400-500 for spouse and I, need to include mr winston and a genset or firewood too. maybe my canoe and a rack....hmmmmmmmmm.......might need that F150hd after all....or a 25 series......hmmmmmmmm.....how much junque do you want to take. bikes, etc? Do you need a canopy? another 200-300 lbs of payload gone or needed.
