Bob ... those are good points. I pull a 24' enclosed trailer with a 1/2 ton Suburban now. Ideally I'd like to start with a Peterbilt 379, 131" from bumper to back of cab (11'). I forgot about the 1' for the lift gate ... 45-11-1-20= 13' for living space. I don't need room for 4 or 6 or 8. There are only two of us. But then I need to be concerned about resale. In amateur road racing ... SCCA regional and national events and Midwestern Council of Sports Car Clubs ... many of the driver show up with a spouse or a friend or a kid ... they don't bring an army to crew the car. I was thinking about having a high enough ceiling in the garage that I could get the about 30" or 36" up off the floor and put tires and stuff between the car and floor either side of the walk through aisle. Those are my thoughts. I'm about 10,000# or 11,000# with the trailer, car, big generator, and equipment. ONe piece of equipment is easier to park at home too.
