I don't tow a foxbody in mine but I do tow a Maverick, which might be a little longer. I have to take the deck lid/spoiler off of the car in order to fit the Yamaha G1A in the trailer with the car; and even then it's TIGHT. 24' Pace. Between the cart, car, and the rest of the junk I take to the track, a 3/4 ton truck is mandatory, 1 ton better. I pulled that rig for a while with a 2003 Lightning and while it had plenty of power, it DRINKS the gas (7.1 mpg average), and it was way too much weight for the truck to stop and handle. When an 18 wheeler passes you at mach 2.2, it was really hard to control the trailer/truck. I traded the Lightning for a 2003 F250 4x4 and it pulls MUCH better.
As well, I have since sold the golf cart and bought a Zuma scooter for a pit bike. Now I have a little extra room in the front for a toolbox and some other junk, compressor, jack, stands, microwave, etc. The scooter is a LOT easier to load by myself.
Would a 26' interest you any? That'd give you an extra 2 foot.
