Ever considered a van. Honda, Kia, and Toyota can tow 3500 lbs per the manual (Honda the best). My boat weighs 2000lbs and I have towed it from the gulf and Canada many times. Works great. Plus you can put all your stuff in the van and lock it up or keep it out of the rain. I got down to the the real late Friday put all my stuff from the boat in the van on one side and slept strteched out on the other at the boat ramp.

I know vans aren't for everybody but the practically of a van for a fisherman is great.

Good luck
