Why do so MANY RV parts come from Elkhart?
Elkhart is the RV capitol of the world. Pretty much all industry is RV related. Building them, making parts for them, hauling them. There are also a lot of RV surplus places in the area. At least 10 that I can think of, their inventory is constantly changing. You can spend more than 1 day wandering around getting ideas and buying stuff.
All of my windows, sinks,waste and fresh tanks, floor,microwave,fridge,and a lot of small stuff came from the salvage places.
I used one of the swivel pedestals for my passenger seat, the seat came out of some Pontiac mini van. Munsywumsy loves it.
