We use to have dealers on the
forum dealer list that would allow you to build your own coach with options you wanted and option pricing on line.
You would start with the base price and add your options and come up with the full price for coach.
Lees RV was one of them but since CW bought into business I see that option has been removed.
I checked a few others and didn't find one on list.
The dealer for Newmar should have a option price list from Newmar for when you order a new coach to be built the list should have the prices.
If I were ordering I would request one from dealer so you can have an idea what you total price will be than deal with dealer.
