RV-4 Pre-buy near Norman, OK?

Can anybody recommend an RV owner / expert near Norman, OK for a pre-prebuy? There is an RV4 I'm interested in at OUN in Westheimer, but I'm in Seattle. The seller has been great, would just like a knowledgeable third party to give it a look before flying out myself

See your pm.

I get a database error every time I try to check them, but as soon as I can get in I'll read it. Thanks!
