At Southern RV, we’re committed to giving you a clear, upfront understanding of your out-the-door cost. The listed Sale Price includes all of our cash discounts and may also includes a Finance Concession for using one of the approved lenders through our Finance Department. In addition to the above price, we have a Documentation Fee of $897 for all RV types, as well as a Dealer Prep Fee of $498 for travel trailers, $698 for fifth wheels, or $798 for motorhomes. New motorhomes are subject to a $3 Lemon Law Fee per the State of Georgia. Taxes are collected based on the location of registration. That's it! No additional freight charges to our dealership, no customer orientation charge, and none of those "ready-to-camp" add-ons like you’ll often find at chain stores!
