Here is an overview of the Keystone Carbon 348 features that make this stand-out fifth-wheel toy hauler the perfect adventure RV. 

Keystone Carbon 348 Stand Out Features 

From the spacious living and sleeping areas to the full bath, the list of Carbon 348 features is long, but the following stand-out features make this luxury fifth-wheel well worth the price tag.

Keystone Carbon 346 Floorplan

With a length of 38′ 11″ and a width of 8′ 0″, the Carbon 348 provides you and your fellow travelers more than enough space to spread out and relax. With three slide-outs, this seven-sleeper is ideal for adventurous families who enjoy being outdoors roughing it during the day but desire a comfortable space to unwind and recharge at night.

The Carbon 348 can sleep up to seven passengers with a 60″ x 80″ queen-sized bed at the front and an electric bed with dual opposing sofas and a loft bed at the rear of the unit. Additionally, the Carbon 348 has a 97″ long sofa to fit an additional guest.

In the private bedroom, you have a wardrobe slide, overhead LED reading lights, and a wireless phone charger. The full bathroom is easily accessible from the bedroom.

Between the garage at the rear and the bedroom upfront, the Carbon 348 provides ample kitchen space for preparing meals without disturbing anyone using the adjacent entertainment center.


After a long day of driving, hiking, or biking, you know you’ll have a comfortable place to unwind and relax with the Carbon 348. Whether kicking back in one of the sofa’s dual recliners equipped with heat and massage features or getting a restful night’s sleep on the soft queen-sized bed, you won’t miss the fact that you aren’t at home. 

With the Keystone Carbon toy hauler fifth wheel, the heated, enclosed underbelly allows you to go out camping in any weather. You can keep the Carbon’s interior at your ideal temperature with the two Omni-Chill dual three-quarter-ton high-efficiency residential air conditioners or the 35,000 BTU gas furnace. You can even take your creature comforts off-grid with the Solar Flex 200 solar energy system. 


Keystone RV’s exclusive KeyTV™ technology is a multi-source signal controller that takes the guesswork out of RV television operation and improves the signal quality of your TV. The sofa recliners allow you to stretch out in front of an angled 50″ LED HDTV entertainment center. The private bedroom and garage each have a TV hook-up if you wish to have multiple TVs for many travelers.

The Carbon comes equipped with 4G LTE and Wi-Fi prep for travelers who need to stay connected. The sofa slide-outs have USB outlets providing more than enough places to charge devices and phones. 


The stylish stainless steel Keystone Carbon 348 kitchen boasts a residential microwave, a three-burner range stove and oven, and a refrigerator with 12 cubic feet of storage. Two 30-pound liquid petroleum tanks satisfy all cooking needs while on the go. The solid surface countertops, large farmhouse-style stainless steel sink, and high-rise kitchen faucet make this kitchen as attractive as it is functional. The stylish soft-close hardwood cabinets with their 100 lb. full-extension ball-bearing drawer glides keep your kitchenware safe and quiet while the RV is in motion.

A portable multi-use table and MORryde flip-up barstools provide ample space for dining. There is also plenty of pantry space for storing food.


Bathroom space is certainly not lacking in the Carbon 348 with its full bath containing a spacious one-piece fiberglass shower, porcelain foot flush toilet, and a sink.
