New 2026 Keystone RV Sprinter 3840LRK 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.
Keystone Sprinter 3840LRK fifth wheel highlights:
- Bath and a Half
- Private Bedroom
- Desk
- Reclining Theater Seating
- Bar Top with Stools
There is much to love about this fifth wheel! Starting with the front full bathroom which has a dual sink vanity for two to get ready at once and heading to the rear kitchen where you will have everything you need to prepare the best home cooked meals. There are also two bar stools at the bar top so guests can socialize with the cook. If you need to get a little work done while you're away, then you can easily get it done at the desk with chair next to the reclining theater seating and the 16 cu. ft. refrigerator for quick access to a snack break. The private bedroom has a king bed slide to lay your head on at night, and if you need an extra sleeping space then you can utilize the sofa slide too. Inside the half bathroom is a countertop with an area prepped for a washer and dryer to be added so you can enjoy clean clothes throughout your entire trip!
The Sprinter fifth wheels by Keystone feature spacious living areas, plenty of storage, and outstanding towability. Each unit is constructed with 2" thick double welded aluminum frame construction, a fully walkable roof and slide out roof, and dual layer insulation to help extend your camping season. The heated pass-through storage includes lockable slam latch baggage doors so you can easily pack your gear, and the one-touch 4-point leveling system features return hookup memory to have you set up in no-time. Head inside to find DynaSpan Marine Grade floor decking, Thomas Payne luxury collection furniture and residential style seamless marbled countertops to name a few comforts. The Sprinter also includes a Suburban tankless on-demand water heater, black out aluminum wheels, plus a 30k BTU furnace to ensure your comfort!
Maybe it’s me. Where I come from I can’t get help. Maybe it looks like I’m not approachable, Maybe it’s because I am old, fat and ugly. Maybe I’m invisible. But I can be standing in an aisle at Home Depot, Lowe’s, Walmart or any other place of business that is willing to take my money looking for something and have a store clerk pass by me without acknowledging me or asking if they could be of assistance. - Billy
