Here's what you need for a support vehicle, at a nearby tow-yard's auction this morning (probably a consignment):

Ooooh! Complete with pedestrian control stanchions!

Mike, I'm beginning to think you know me better than my wife.
Actually, take one of those, box the frame, go with MGB-GT V8 brakes up front and a Rover V8 with a 5 speed, and I'd use it for a tow vehicle!
Problem is this - 4 cars, 3 garage spaces, and Mrs. Midget is already whining about the trailer in the back yard.
And bringing up her shoe closet is not an effective defense.
