Pontoon boats weigh much less per foot of length than fiberglass hulls, I believe. But if my small truck nicely handles a 2000 lb. 16' boat, would it have a problem towing a 24' 'toon of the same weight?
I had a Ranger pick up truck & towed a 20' pontoon. Alltho it was a light boat the wind drag just about killed the poor truck. it was worse with a headwind. It,s like towing a parachute.
