Not to stick my nose in but when i was building my carrier i was moving a stripped hull around on a landrover defender 110 with a ifor williams trailer with no problems was towing at 50mph, i would say the hull would be about 2 tonns if you think the tracks and running gear is about a tonn the engine gearbox and all the extras would be about 1/2 tonn ish and a complete carrier is about 3.5 tonns, iam think iam on the high side on my weights but would rather guess and take something bigger to tow it with, looking at that photo you have put up i would say you would be looking a around a tonn maybe just over?
maybe you should strip it and put some in a trailer and some in your truck if you have the space and time to do that?
good luck
