sorry cant help with that model but the wife and i just done a total rebuild on a 68 tailor craft tt,,,,and you are correct hardley any info at all on them,,...
but since i have torn one down to the frame and rebuilt it i can say they are a decently built trailor...i have seen better and seen a hole lot worse..lol
but as far as price goes i think they are worth what someone is willing to pay for them,,,,,,
goodluck and please post some pix when ya can....
