Welcome, Congrat's on your future purchase.
Don't know that I can advise on what would "finalize" the purchase other than to say perhaps you should use the Buyers Guide (which can be found in the upper right hand box at the top of this page, click on "MORE" then Click on Documents" scroll down to Buyers Guide) to at least give you a idea of what your projects might be.
For me, the first things I would make sure are looked over/repaired would be the Axle
, pack the bearings, frame, gas lines, electircal...... Then bring on the make over factor!
Again, Welcome! Glad you joined us..................
