Looking really good. I am thinking I should have used the poly busings as well. I used sleeper mount bushings from Kenworth that look about the same as yours, however,they compressed about a half inch more than I anticipated and now my opening to the cab is lower by 1/2 inch. The rubber boot will probably handle it. How much do you think you box weighs? I don't know what mine weighs but I think its much heavier than I anticipated. Keep the photo's coming. MMM

I was hoping this thing would be done already, but you know how life gets in the way, right now I am at an Army school, so it will have to wait till I get back. According to Road Rescue (the people who made the box) the box weighs around 5500 pounds empty. When I completely removed everything that was not bolted down and weighed it it tip the scales at 10053 pounds. I am guess the van cut away chassis must weigh about 5k as well? I figure that with ten poly mounts, it should not settle too much more than an 1/8 inch. They are pretty stiff, but should still absorb some twisting and vibration. Since this is truck is going to be used mostly on paved surfaces, I am hoping that I have accounted for enough flex for a rigid cab to box mount setup as recommended by Road Rescue.
