Well I'll just say that if you have a single rear wheel truck then your going to be limited to a GVWR on a toy hauler of about 17K or even less because of the age of your 01. No 14ft garages on any of those that I know of. If you have a dually then that will open up a few more but because of the age of your truck, you'll still be limited because the 14ft garage models are generally heavier than what your truck will handle. The one true 14ft garage toy hauler I can think of is the new Weekend Warrior 4100 or 4250 models. There are some 16ft garage models out there also all of which I doubt your truck can handle. Most haulers that size will have a pin weight of 3600# and up which I believe narrows trucks down to a dually in the 2010 maybe up to current model years.
