1993 Foretravel Grand Villa 36' tow rating / gcwr?

thanks, I sent the vin to Foretravel asking for the build sheet on this rig but they said they 'don't get involved in private sales'. I had read on other forums that FT was good about providing info (nothing beyond point of sale/ownership ... just what rolled off the assembly line) but I guess not.

I think as much as I love the style of these old GV's, I may look for something with a larger diesel/newer class a that can handle a ~5k lb toad
