Found a new site -- this is deep in the heart of RV manufacturing territory (also Amish Country) in Elkhart, Indiana.

Looks like good pricing.

Maybe Ray Horner can tell us more about this store as he's from Elkhart too :)

I've ordered from these guys and was very pleased. Shipping was reasonable and items packed well, prices were great, and service was good. I even had a problem with a power vent and they sent me a new motor for the vent without questions. I would highly recommend them if you can't find something local.
