New 2026 Keystone RV Montana 3900RK Fifth Wheel

The Colton RV & Marine Advantage

No Hidden Fees RV and Boat Pricing:

The Colton RV & Marine Advantage (What Others Don’t Tell You).

Buying an RV or boat should feel exciting — not confusing. That’s why we created No Hidden Fees RV and Boat Pricing, part of the Colton Advantage.

Too often, shoppers fall in love with a unit online, only to be hit later with surprise fees like freight (getting the RV or boat to the dealership) or prep (the cost to clean, inspect, and ready the unit for you). These extra charges can add $1,000 to $10,000 to your total — and most dealers don’t mention them until it’s time to sign.

At Colton RV & Marine, we don’t believe in that. That’s why we created Colton Advantage Pricing — our commitment to transparent, all-inclusive pricing that respects your time and your budget.
