Grand Kitchen

Outside Kitchen

This grand kitchen offers the cook their own space to prepare and serve meals from the large L-shaped counter peninsula bar with stools, and the large pantry and curio will come in handy as well. Dining is also available at the free standing dinette with four chairs and some might even enjoy sitting on the hide-a-bed sofa sleeper. Also available for seating are the theater seats which are equipped with heat, massage, LED lights and USB charging. The master bedroom offers a king bed with storage underneath and additional wardrobe storage plus a space prepped for a washer/dryer option. Having a separate living area from the kitchen gives everyone room to spread out, and outside there are two power awnings offering additional outdoor living areas protected from the elements. The cook will enjoy the outside Grill-n-Chill outside kitchen as well.

With any Keystone luxury Alpine Avalanche Edition fifth wheel, you will experience wide-body construction that allows you to stretch out and stay awhile during any season thanks to the Polar Pack All Season Protection that includes a heated and enclosed underbelly, an Astro foil reflective layer on the roof, front and rear walls, and two static attic vents, plus more! The interior offers hardwood slide out fascia with wood accents, designer upholstered window valances with custom wood window frame, plus your choice of modern interior design. There are many more Keystone exclusives, like the Tru-Fit slide construction, the in-floor heating ducts, KeyTV™, and much more to bring you a full-packed, luxury fifth wheel!

What Other Customers Are Saying

Great Service
Went to Imperial for an AC check up. They cleaned our unit, fixed my toilet, and everything is working in top order! They were also very responsive to my questions! Will definitely use them for ALL our RV needs!

Candy
Great Help
After over years of no camper, my wife and I went to Imperial RV and purchased 4th unit from them. We have known the owner Denise for over 30 years and Zach her son in law for 20 and have never been disappointed in our purchases. I have always been picky about something every purchase and they take

Scott
Highly recommend
Imperial RV is NOT your typical RV dealer. I recently traded in and purchased a TT. My experience here was awesome. Things like customer service, educating you with the market, showing LOTS of patience and making me feel welcome the minute I walked in. Absolutely no sales pressure and willing to work
