Tough decision for sure..
OK, I glean from your post you can either take $2000 to bring your present 93 coach up to snuff, OR pay $20,000 cash for a 2001 coach then spend that $2,000 to bring that coach up to snuff.
well I would think consideration of your present financial status would pretty much dictate the best route to take.
For me, with all the future uncertanies we're facing, I think I'd be inclined to keep my $20,000 tight to the vest for any future contingencies that may arise, and invest the $2,000 in bringing my present coach up to snuff.
We have 75,000 on our 2000 coach which could use some minor cosmetic work, paint, decals etc. in the $2,000 + price range which I may have done sometime in the future, but then maybe not.
Anyway I wish you the best of luck with your decision and safe travels...
