Joe H, thanks for the link. I have seen that book somewhere before (probably here) but need to remember that it exists. As typically happens the book dimensions for the 3600 are with differnet size tires than I have but I think there are enough dimensions that I can calculate the numbers for my configuration.
That link gives dimensions to the bottom of the pumpkin and the top of the frame at full load, so by subtracting the two, you could get the distance from top of frame to bottom of pumpkin and use ratchet straps to compress the suspension to that distance.
