The best way to tell about a manual trans. is to drive it. If you get excessive whining noise in all gears except high it indicates bad brgs. namely the front drive brg. or the brg. between the shafts. If the gears clash or grind when you shift to any thing but 1st. or reverse it indicates bad syncros. If it jumps out of gear it could be bad gears or thrush brgs. I realize "easy to o-haul" is a relative term. It depends on the mechanics expertise & facilities. Compared to a SM465 these are real easy.
