Survey says... 1T for 5th wheel & 3/4T for BP Toyhauler

The $ between the two is nothing if you order but off the lot it's a different story. Not many 1T short beds on the lots in these parts. Well I'm towing towing 8k with a gasser in the Rockies in a few weeks and that should help me at least decide on the gas or diesel.. Towed the same trailer last year in the same area with my CTD so I should have a good comparison. Really don't want another diesel and trying to keep my next trailer under 35' for storage reasons.
