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.

Grand Design Imagine 3100RD travel trailer highlights:

• Rear Living Area
• Theater Seating
• Free-Standing Dinette
• Roof Mounted Solar Panel

The rear living room on this Imagine travel trailer is just what you'll want when you're looking for a little down time. This room has opposing tri-fold sofas within slides, theater seating, and a TV. Another place that you can sit down at is the free-standing adjustable dinette. You can sit here with a fresh cup of coffee in the afternoon as you map out your hike for tomorrow. The kitchen offers you a flip-up countertop extension, a microwave, a three-burner range with oven, a 10-cubic foot 12V refrigerator, and pantry to help you make meals, and there is a private bedroom with a 60" x 80" bed to rest on at the end of the day.

Just imagine leaving the world behind and secluding yourself away with your favorite people in your Grand Design Imagine travel trailer! The Imagine has been designed to enjoy camping and includes a high-capacity furnace, a heated and enclosed underbelly with suspended tanks, a designated heat duct to the subfloor, and a high-density roof insulation with attic vent. You'll have a large panoramic window to let natural lighting in and an adjustable Power Awning with LED Lights for those night gatherings. The exclusive drop-frame pass-through storage compartment is going to allow you to bring along lots of equipment, and the universal docking station is an all-in-one location for utilities and hook-ups. You'll also have oversized tank capacities so that you can fill and empty your tanks less often.
