89 Burb Eval - Should I or not?

[swissarmychainsaw]

I'm going to go look at an 1989 GMC Burb tomorrow, and want to know what I should look for.

Sounds like the guy dropped some coin making it off-road worthy.
Here are the specs:
145K miles
4x4
350 TBI & (TH3550) it seems weird not to have an 700R4
[ I just rebuilt my 84 chev 700r4 and don't want to go through that again ]
1 Ton axels frnt and rear
Dana60 Front with hi-pinion AND hydraulic assist steering.
14 Bolt Rear with disk brakes. 3.73 gearing
Line Lock.
Dual Shocks on all corners.
Frame reinforced at Steering Box.
Gas Tank swapped out for one from a Suburban with a 454
Front and rear hitch
off road bumpers
4" lift

Interior sounds basic and rough but the rest of it sounds ready to climb over something! Crank windows, no ac or flash from what it sounds like.

Owned chevy trucks but never a burb... Burb owners help me out, what to look for?
