Karen, it doesn't look BAD but remember that RV appliances are expensive - and on a 23 year old camper you need to know how old they are. The A/C shroud on the roof looks new so that might have been replaced recently. The refrigerator can still be fine, but make sure it works on both AC and propane - it's $800 to $1100 to replace if you can't do the installation yourself.
The water heater if original as past due for replacement. Be sure YOU inspect every appliance carefully. Oh and be ready for the "I don't have any propane in the tanks" - bring a spare cylinder! Run the stove, oven, water heater and furnace (if the salesman starts to run away when you turn those on... don't continue the test!) Insist on hooking up to a water line and testing for plumbing - or if you know an RV tech you can trust (HA!) pay to have a certified evaluation of your systems. $10K... well it could be worse, but remember that's their price not what you're going to pay.
The axles look fairly decent - not really sagging down, but you need to ascertain that they haven't taken a "set". Here again these do have a finite lifespan so if they are original they've got some serious years on them. The damage on the lower front panels is not as expensive as the upper segments to replace if that's an issue for you. One thing I noticed on the exterior was some wrinkling on the lower skin near the back on the roadside. That could just be the angle of the shot - or it might be an early sign of the dreaded rear frame separation.
