Jared. Thanks for the comments. You bet I like the transfer too. And the setup with two trailers would even be more fun. The Beall video shows the stirrup arrangement for the transfer box locks and that doesn't look complicated. I have a small gearbox that came with a winch from RC FWD and I think it will work for the transfer system. I've got servos coming to try the high lift tailgate so we'll see how that goes.
Neil. I can imagine what a mess that would make dumping the box in like that. I think I'll try an arrangement with the truck tailgate lock so when it opens the transfer tailgate locks it also locks the transferred box in. Hope that makes sense.
I guess I should have photoshop'ed my truck in there pulling the two trailers.
