i'd gladly tow a 2 ton truck over a full sized school bus any day. done it. won't do it again. my next projct is going to be a tow dolly that i can put the truck front end on so i can atleast have one axle with brakes. i'm thinking about a internal tire mount kindof like the trailers for the flotation tired spray rigs. mainly because i don't know how to make it under the 8.5' wide and able to accomodate a 8' truck. kind of like this
but still have it able to drag a car/pickup onto it between the wheels. im thinking about using a walking beam suspention with two axles and truck low profile tires.
