Thought this up last year, just now remembered it, made an improvement , and drew it. Let me know what you think It would of course have to be built specifically for your own trucks ride height. If you lift it your truck a little later on you could place a spacer ontop the beams. For lowering the truck, airing down would be the most obvious choice.. loading the suspension, or using air bags would probably have good results too. Maybe if it works good, add on some sort of roller hardware? Maybe make a track w/ directional wheels to roll it back and fourth? Heres the computer sketch I don't know if anyone has thought of/posted this before but figured why not. What do you think? Anyone want to try it? It would have to be measured perfectly and tested before you made it permanent Morgan PS- Yeah, i know it looks like a panel/utility truck. =P EDIT- Where the beam sticks out off of the rest of the wooden structure, you could have a hinge for the arms to fold to the side, but it would weaken the arms.. Maybe with some thinking it would work.
