The issue about ordering from a place like that is that if something is defective, good luck getting it fixed under warranty unless you drive back to the dealer. Most places will not honor a warranty unless they themselves sell the rig, and if they do, the RV will be last on the list, likely sit for months.
I'd rather use the quote as a starting place for negotiations than buy out of state, have to deal with licensing and registration, and then find some shop that you have to pay out of pocket for repairs.
