    FTC-Compliant Pricing Standard

    Big-box corporate RV dealers advertise low hook-prices online, only to add $2,000 to $4,000 in surprise fees in the finance office. We have declared war on those corporate games.

    The Federal Trade Commission (FTC) deems hidden, surprise dealer fees to be deceptive and illegal. Our pricing remains 100% upfront, transparent, and honest.

    The only items NOT included in our advertised price are standard governmental fees (Tax, Tag, Registration). All dealership prep fees are fully absorbed.

    Honest Pricing vs. Corporate Chain Stores

    • Freight, Factory Prep, Detail & Walkthrough: 100% INCLUDED (Chain Stores: Extra $1,900 - $3,800)

    • Filled Propane Tanks: INCLUDED. Ready to cook and heat on day one. (Chain Stores: Extra $100 - $200)

    • Genuine Interstate Battery: INCLUDED. Heavy-duty standard. (Chain Stores: Extra or cheap generic)

    • Dealer Document Fees: $0.00 ZERO (Chain Stores: Extra $499 - $999)

    All of this is completely included in our selling price. We do not charge extra for mandatory package add-ons.
