Jansen,
Figure your total towing weight at 33 to 3500 lbs depending on how much you put on board. Before I get flamed for saying 3500 lbs, I know people who use the boat as a trailer when on vacation.
The real issues to deal with are the ramps you plan to use (hall out with ballest full) and the roads you plan to travel. Generally, the 26C, S, and D can be towed with 6-cyl vehicles almost anywhere. Ours was being towed by a 4-cyl chevy PU by the previous owner in Clearwater, FL. He was within 2-miles of a long, not steep ramp. From memory in a past life, towing weight ratings are listed at a 15% grade as required by the National Highway Traffic Safety Commission. Less hills/mountains = less engine required.
