Remember the big impliment stuff is made for equipment that weighs 3-4 even 10 times what our trucks weigh and are made to survive Billy Joe Bob's thoughts on "I can do it!". There are a lot of big heavy trucks running the proposed set up most of which when you look at them you say no way will this work, but the do and do it well. You can scutinize things until its a bad idea, I don't care what kind of suspention you build. If you don't mind trying something more than once try it that's how we learn what works and what doesn't, the worst you have to do is cut it off and try again. And besides what doesn't work for one truck or driver may kick your butt by another truck or driver.
The bus I ride is so short it is a yellow Smart Car full of squirrels, monkeys and clowns.
