2026 Keystone RV Montana High Country for Sale #31107

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 dealer) 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. Keystone Montana High Country 290RL fifth wheel highlights: Triple Slides Full Bath 12V Refrigerator Front Private Bedroom You'll love camping in this fifth wheel with a rear living room and triple slides for ample interior space!
