Anybody towing pontoon boats out there? I'm getting a 21' fishing pontoon and was wondering if with a class III Xterra Tow Hitch - would it be stupid to pass on the trailer brakes? I think the trailer and boat weight will be around 3200 pounds, total. Thinking about Timbrens too, just not sure if I really want to spend on things i don't need. I just want to make sure it's safe at highway speeds and on uneven roads.
