I have the Prolite Plus S. I have a 3500 tow limit. The S comes in at 1390 empty. It obviously tows like a dream. I visited the factory and was very impressed. I wouldn't advise riding the edge. They have lighter options. But obviously if that isn't the route you want to take, I would advise looking at other tow vehicle options.
I have purchased american made for the last 30 years and my last new Jayco drove me over the edge.
So with that said, there are other Canadian options. I am thus far extremely pleased with my Prolite and possibly the best RV purchase yet.
Good Luck and happy camping!!
