FTC-Compliant Pricing Standard
Most big-box corporate RV dealers advertise a low hook-price online, only to hit you with $2,000 to $4,000 in surprise fees when you walk into the finance office. We have declared war on those corporate games.
The Federal Trade Commission (FTC) explicitly deems these hidden, surprise dealer fees to be deceptive and illegal. Corporate bait-and-switch tactics violate federal consumer protection standards, which is why our pricing remains 100% upfront, transparent, and honest.
The only items NOT included in our advertised selling price are standard, non-negotiable governmental fees (Tax, Tag, and Registration). Every single dealership prep fee is fully absorbed into the price.
Honest Pricing vs. Corporate Chain Stores
• Freight, Factory Prep, Detail & Tech Walkthrough: 100% INCLUDED (Typical Chain Stores: Extra $1,900 - $3,800)
• Filled Propane Tanks: INCLUDED. Fully loaded propane system is filled and ready to cook and heat on day one. (Typical Chain Stores: Extra $100 - $200)
• Genuine Interstate Deep-Cycle Battery: INCLUDED. Heavy-duty American reliability standard to protect your electrical system. (Typical Chain Stores: Extra or cheap generic junk)
• Dealer Document Fees: $0.00 ZERO (Typical Chain Stores: Extra $499 - $999 hidden dynamic fees)
All of this is completely included in our selling price. We do not play corporate trick games, and we will absolutely NOT charge you an extra $1,995 for a mandatory "Let's Go Camping Package" like the big chain stores stick on your bill at signing.
Recreation USA is proud to stand as one of the few remaining independent, family-owned RV dealerships in the country. We don't answer to Wall Street investors or corporate boards—we answer directly to you. That independent freedom is exactly how we are able to throw out the industry rulebook, absorb factory prep charges, and offer completely transparent, honest pricing on every single luxury fifth wheel we sell.

Amy from Cheraw, SCTHE BEST RV DEALER
Patrick was a great pleasure to deal with! He kept in contact with me, gave us private time to look at our RV and discuss things and was very very personable! Jonathan went above and beyond for us and your kindness is greatly appreciated!! I HIGHLY HIGHLY RECOMMEND RECREATION USA if you are looking -
Timothy from Bladenboro, NCThe BEST service!!!
Recreation USA has been so smooth to work with! They found us an amazing camper and gave us all the information we needed to make a purchase. We did not feel pressure or any type of pushy attitudes during the time we were there. Alot of other places you go to are money driven and do not focus on building -
Deborah from Myrtle Beach, SCOutstanding!
From the initial visit to the delivery of my new 5th wheel the service was outstanding! John showed me around initially and Nathan spent several days and a lot of time explaining the different types of trailers and answered all my questions. Arisa in the office was very attentive to all the employees
