If you walk through a lot of RVs you can see cheap. Go to RV shows in older clothes.Don't hesitate to look under, take notes, check quality of drawers, cupboard bottoms. If you see cheap in visible areas you know there will be cheap in hidden areas. Ask to have slides run in and out. If something isn't working in one particular RV I try to find another dealer with same type unit. If the problem isn't working in a second unit I don't listen to BS about it will be fixed under warranty. You really need to do your homework and you will come out OK. Don't get caught up in oooohs and aaaahs on how nice it is takes notes.
