So I have flat towed our IIA for years so I am good to go there. My question to all of you is whether or not you find it necessary to detach rear drive shaft or just free wheel hubs and put t-case in neutral?
I always removed the rear d-shaft at the rear diff just in case but I need to tow it tomorrow for a short distance and do not want to fuss with the drive shaft.
I've been towing Series around on their wheels using an A frame for thirty years and thousands of miles and never had a problem. The only thing you absolutely have to do is engage the transmission in fourth gear and put the transfer case in neutral. Forget to do this you will damage the transmission.
There is an obvious reason why the transmision gets damaged if you leave the transfer case in gear and put the transmission in neutral (the mistake most people make). Towing with the transfer case engaged causes the gearbox rear main shaft to rotate without the lay shaft rotating. No oil is splashed around in the gear box and the result is that the bronze bushing between third and fourth gear overheats and fails.
Series trucks tow very sweetly and the steering follows the tow car ver precisely - provided of course that the steering relay and box are in good shape.
