Purchasing a used TT from dealer

I saved easily hundreds of dollars by having the dealer hook up to water & power prior to my comming to do the final walk through. Even though they assured me it had been gone over. I found two broken water lines, a ruptured water heater, bad batteries and a missing ousside stove upon pick up. How motivated would they have been to fix anything after the sale? Not very. IMHO Coachman is an upper middle market unit. Is the fridge working? Do the holding tanks hold? Furnace, Oven, water heater? Check for water damage everywhere. Ask them to do a pressure test for leaks. Best of luck
