[#90-GTSC]

I'm looking for a HDT conversion to pull my 24' enclosed trailer (might upgrade to 28' trailer) and race car and that we can live in at the track. I found this up in Grand Rapids, Minnesota.

1989 White Peterbilt
2002 24‘ conversion package
425 HP CAT engine
9 Speed Transmission
Propane Furnace
Roof Mount Air Conditioning
Satellite TV ready
3/4 Bath
Queen Size Rear Bedroom
Sleeps up to 6 People

Current owner bought it five or six years ago from a guy in Rochester, MN. Don't know who did the conversion. There are no screws or rivets on the sides, appears aluminum sides were butt jointed and glued to the studs. None of them look like they are coming loose. No evidence of water leaking inside, the trucks lives outside summer and winter.

Here are some of the issues:

Pax windshield is cracked
Tractor cab A/C doesn't work (is fixing it like fixing a Suburban A/C unit or more complicated/expensive?)
Pyrometer doesn't work (Is this expensive? Critical that it should work?)
The Onan generator is out and apart; engine ran fine, but no power from the generator
During the test drive sounded and felt like wind coming in around pax door (weather stripping?)
It has lots of miles.

Seller told me that he put new tires on all around in last year or two.

I'm going to put 3,000 to 5,000 miles a year on it.

What do you guys think? What should I be concerned about? What should I dig into further? Thanks for the help and the comments.
