The central kitchen and living area create a welcoming space, highlighted by a U-shaped kitchen with a Furrion three-burner gas range, 16 cu. ft. refrigerator, overhead cabinets, plus a nearby hutch and pantry. A flip-up counter extension adds extra prep space, while a slide-out dinette with four chairs sits across.

What Other Customers Are Saying

Wonderful
The staff at Mountaineer RV Center was absolutely wonderful! It would be hard to find a better fun family business. We were made to feel important. They will answer all questions and fulfill any requests without hesitation. They made sure we were comfortable and ready when we left.

Todd
Great Experience
I bought a truck camper from a private seller and it unfortunately had a lot of water damage inside that was hidden from me in my first initial inspection. This was heart breaking as me and my girlfriend are planning on leaving for Alaska soon. Fortunately some friends recommended Jimmy Garris to me

Cyrus
Very Professional
Was traveling from out of state thru that area. Had issue and needed parts to get me back home 12 hours away. Can’t remember young man at parts counter name (sorry). Was very professional in every way. Please recognize him for his outstanding customer service
