We bought our new 3650 last Sept ,used it for aweekend to find any bugs; there were so many that we took it back to the dealer and told them to keep it for the winter and fix them.First (E)tires not (G) as advertised ,Windows would not close and lock,still waiting for one to be replaced, carpet on fireplace slide all fraded and coming off. They used three small pieces of carpet-NOT ONE-,in the little hallway from the bedroom to steps the seams had 1/4 inch gaps because the carpet was coming apart,toilet replaced,two furnace hoses were not attached.Well its May, and we got it back ready to use.Been camping for four days bathroom tap started to leak (fixed)now kicthen faucet starting to leak,and now the onepiece mega shower is showing hair line cracks( have fun fixing that one).This is our fourth rv and thought it would be our last , the one we would retire in .Now all I'm hoping is to get it fixed and trade it off.
