There are many places that have RV "Stuff" Of course sometimes you need to define "Stuff"
Camping World (of course) many RV dealers, "Super stores" (Personally I try to avoid Wall Mart, don't like the company) Sears
Hardware stores R.E.I. Garner Mountain (Spelling) to list but a few.
One thing I should note.... I decided I wanted an outdoor hot water heater (Coleman's instant heater, darn near continous flow, 40 gallons on one 16oz bottle of propane and one battery charge) so I went to a Coleman outlet store
The "Regular Price" (179.95) was IDENTICAL to the price at my regular RV store (WOW! Usually you slap a RV sticker on it the price goes... Well... UP)
I got it anyway.. This weekend is the Red White and Blue sale, 15% off give or take a percent (I thikn it was 149.95)
