We mount cabs rigidly with S10 brackets and cushions. Makes for a very stable set up and keeps panels aligned. Would NOT mount this way if truck is going to be used on uneven ground or where frame is repeatedly twisted. 99% of our rides now are driven on paved, even roads so not a problem.
S10 brackets can be shortened and welded/bolted to an AD frame:
