I've just added a page to my website that has a map of the RV surplus stores in the general area of Elkhart, IN. I've done my best to verify that they still exist. If anyone knows of any stores in any part of the country and would like them added, just let me know. I know there are some RV wrecking yards out there too.
Please, only places that you personally know exist and/or have visited in the last year or so.
