Your truck should have no problems at all towing the TM, I doubt it would have with the 305 as I tow my 1986 25 with a 4.3L Chevy Blazer. On that TM though, you had better check all the wood in it for rot! If it's been sitting for a long time, it might have the same problems as mine did. Also, check who made the appliences in it, in particularly the water heater and furnace. Mine are both made by companies that are no longer in business anymore and I cannot get any parts.....so if they go bad, then they have to be completely replaced. (Might bring that up when the issue of what you're going to pay for it comes up as well). If you're wondering what I'm talking about with the wood rot you can check my web page at:
