Re: towing
I have owned three different pontoons and obviously, towed all of them. I currently tow a 24 footer with a Chrysler Pacifca which does just great. Up hills, down hills, on ramp....no issues. We are, however, in a slip the last two years, so I don't tow much. I also towed with a Jeep Cherokee a 20 ft toon I owned and then later used a Suburban. They were all adequate, with the Suburban of course being the best.
The ability of your truck will also somewhat depend on what brakes you have, suspension, and how confident you are in your abilities. For shorter distances, you will be fine. You might have issues with some ramps with the 2wd.
