To get lights for this tow, I spliced two trailer cables together so that each end had a male connector. Then I plugged one end into the trailer connector on the deuce and the other on the xm757's trailer connector.
Didn't have brake lights for some reason, but everything else worked. Used the 4-way flashers so much that it probably didn't matter anyway.
Four propeller shafts were removed for the trip and the rearmost axle was suspended with a chain to reduce drag while turning.
Towed the 8x8 over 1,000 miles this way.
Weight distribution: Deuce was 20,000 lb and 8x8 16,000 lb
