Old (1984) TM

Okay. I'm new to this popup thing. I've used a tent all my life but now the kids are 3 and 4 and with the dog...well, the family 'tent' just isn't working out so well anymore. I've been researching popup's and I really like the TM, but I don't like the price. There is an old one at a local dealer, a 1984 27'. Does any know anything about the first few production years of the TM's? They want $2900 for the unit; I havn't really checked it out for working appliences and rot or rust yet. Should I or shouldn't I consider it? Yes, no, Run away screaming? Stop being so cheep and spend a little more for a newer model? Thanks! :-\
