To elaborate on (Utah) Dan's reply, you are the only one who knows your tastes, and even you don't yet know enough about RVs. I'm certainly very happy with my V10 in my Bounder, but I don't know how good the V-10 was in 1994. Still, you'll want plenty of power to move the vehicle, and V-8s are usually a bit weaker (there are exceptions, of course).
I'd suggest you look at overall condition of the unit, and especially at the floor plan. Spend some time (preferably while actually in the unit) visualizing how you would use the various features/amount of space, especially for cooking, sleeping and when rain/inclement weather keeps you indoors at the campground. Look, too, at storage space, trying to anticipate what clothing/dishes/linens/tools/amenities you think you might want to take along, including grill, lawn chair, cameras, musical instruments, paper plates, dishes to eat from, cookware, CD/DVDs, books, etc.
I'm sure others will chime in with more good thoughts.
