Welcome Larry, glad you found us. There are several of us from Oklahoma here, so you know your in good company, nationwide!
I just got my 92 ward Senator about 3 months ago, got the seats out and tagged/insured, floors chalked up so I 'll have an idea if everything will fit, but that's about it so far. Done walked around it a thousand times and have a pretty good idea of where my tanks, generator, etc is going.
There are some sharp minds on this site, so don't be afraid to ask questions. And good luck with your bid.
