Keystone Montana 3121RL Review

One of the best fifth wheel options out there.

When it comes to top-of-the-line luxury in RV form, the Keystone Montana 3121RL holds the throne. This is a fifth wheel that pulls out all the stops to provide RVers the best in towable comfort. In fact, we’ll see some features on the Montana you might not find in many residential homes. We’re talking lots of space and excellent features.


We start in the kitchen, where, before getting into the details, Tiffany kindly offers some panoramic views of this enormous space, including the kitchen island and surrounding dining area. Think countertop space and overhead storage to the max.

The Montana cooking area features a three-burner stove, oven, and a large overhead vent that conveniently opens up additional storage space for kitchen and cooking items in a hideaway cabinet. And speaking of hideaway, the cabinets in this area pull out to provide even more additional counterspace. There’s plenty of room for prep and presentation.

Other kitchen features include a luxury wine holder, pull-out drawers, a mounted microwave, and a double sink.

Living Area

Featuring a pull-out couch and two reclinable entertainment chairs, the living area of the Montana is perfect for entertaining guests or cozying up for movie night. Heated seats on the reclining seating add to the level of comfort while watching the 50-inch mounted television. And, on the windows, blackout shades keep your privacy, especially when converting the tri-fold pull-out couch into a bed.

Next, check out the electric fireplace is located beneath the entertainment center. Not only does this add to the comfortable aesthetic of the living room, but this can also reduce your propane usage when heating the RV.

Last but not least, the theme of extra storage continues with overhead cabinets perfect for blankets, pillows, or anything else you’d prefer to keep out of sight when not in use.

First impressions of the bathroom? Impressive attention to detail. In fact, Tiffany immediately praises the full-size door entering the bathroom, which features modern framing a sleek handle. Jack and Jill sinks and pull-out mirrors offer plenty of space for a couple, and there seem to be additional cabinets or cupboards wherever you reach.

Next up is a porcelain toilet with a foot lever and a full-sized, spacious shower with triple-pane doors and a moveable showerhead. The Montana bathroom provides all the privacy, luxury, and space you’d want.


Going right along with the main theme of spaciousness, the master bedroom fits right in, starting with a king-size bed that features a cushioned headboard. Also, note the matching peek-a-boo windows on either side of the bed.

The main closet opens up with sliding mirrored doors, and inside you’ll find shelves for clothing, a small laundry shoot, and a full hanging rack for suits and dresses. An auxiliary closet includes space and hookups for a washer and dryer.

Outside Storage

With all the luxury featured on the inside of the Keystone Montana, you’d sorely miss elements of comfort on the outside. Luckily, the Montana doesn’t disappoint. Large storage bays have plenty of room for the grills, camping chairs, mats, tents, and firepits you plan to bring along to make for an incredible outdoor hangout area.

As Tiffany notes: wherever you choose to make your backyard—on the woods or on the beach—the Keystone Montana is a great RV to bring along as your home away from home.
