Selling caravan parts

I was thinking about trying to sell caravan parts in my town. I rented a small storefront and ordered a decent number of a lot of the standard parts for caravans and campers. I did a small mailer to all the people in town who I know have caravans and campers and would be interested in shopping locally for them. The closest place to get parts was over 100 miles away, or they could order them on the internet and wait a few days to get it. This way my store was close by and carrying the basic parts, they would shop here.
