Interior looks good, no orange shag carpets!! Make sure tires are the right type and less than 5-6 years old by date codes with no sidewall cracks. RV tires go bad sitting parked and can come apart whipping underside stuff with steel belts. You will probably need the RV generator and roof AC working reliably. The converter/charger and house battery(s) may need replacing. Modern converter/chargers do not overcharge/boil out batteries. Flush brake fluid as it collects moisture leading to brake fade on long down-grades. You probably know the rest. Have fun with your new hobby.
