New or used? Either way run all appliances and make sure they work. Check the tires slide covers awnings, ect. Look for loose or faulty trim pieces.
Just take your time and check everything. I'll bet you'll find something. Someone told me that if there are 10 RVs in a CG, 9 have something that needs fixing.
While shopping for a rig, I notice a lot of new RV need repairs, such as closet doors off track and no cocking around showers, etc. Husband is going to Teflon tape the fittings. They don't seem to do that.
