Let's dive right into the features of these two beautiful units:
The Coach
Painted the incredibly attractive, and hard to find, Cayenne paint scheme, this 2017 Entegra Cornerstone 45A luxury coach has all the amenities folks ask for while traveling in style. Whether you plan to travel privately, or frequently entertain guests, the Cornerstone leaves no stone left unturned with zoned HVAC systems, flexible in-floor radiant and forced air heat, 4 TVs, 2 bathrooms, and all the storage you could ask for, inside and outside this true luxury home on wheels. We'll be highlighting additional features, but please see the photos of the spec sheet for the seemingly endless, thoughtful equipment on-board.
Starting with the heart of the unit, this coach is built around a Spartan K3 raised-rail chassis. While so many Class A RVs still lack power, this Cornerstone diesel pusher features the legendary, reliable Cummins 600 HP, 1,950 lb. ft 15-liter engine, paired with Allison's bulletproof 4000 MH 6-speed transmission. It's an incredibly proven drivetrain combination that even makes driving through steep passes quite comfortable. The current owner purchased this coach in 2018 from the original owners, with just under 9,000 miles. Since then, the owners have consistently added around 5,000 each year. With 150 gallons of fuel on board (can fill-up from either side of the coach), and averaging around 6.5-7.5 mpg with the trailer connected, driving range on this luxury bus is incredible. The coach is serviced each spring and fall, to make sure it's always ready to go when needed. When not on the road, this Cornerstone is always stored inside a climate-controlled building to keep it looking as new a possible.
Inside this coach is where the creature comforts really start to put smiles on faces. Once parked, touch a button, and the coach self levels. Cherry wood cabinetry & trim, along with porcelain tile flooring with granite inlays offer immediate warmth to the space, and speak to the quality of this coach. Leather seating, quartz countertops, and abundant, thoughtful lighting, help provide comfort and set any mood you're looking for. This Entegra Cornerstone features the 45A interior layout, with the optional business desk and fireplace (excellent for supplemental heat or getting the chill out) in the front seating area. A reclining leather sofa across from the desk offers additional seating and sleeping options for guests. The owners also utilize an additional inflatable mattress for overnight guests. There's simply a TON of room.
The kitchen & dining area is spacious, allowing ample walking room and pantry storage to prepare meals and entertain. The large convection microwave is helpful for heating AND baking, and the residential fridge is huge; it's sincerely larger than mine at home. The induction cooktop makes quick work of any stovetop needs, and doesn't sacrifice conveniences form home (note the cooktop crack, but does not affect operation). Cleanup is a breeze with the dishwasher and large stainless sink.
The interior tour continues with the ingenious half-bath. If someone is sleeping in the bedroom, or you just want to close the bedroom door while entertaining, the additional bathroom space allows for unmatched privacy and convenience. The rear bedroom area proceeds with the luxury found throughout the coach, with a king size Tempur-Pedic Cloud Prima mattress and additional cherry hardwood trim throughout. The full bath sacrifices nothing from home with an incredibly spacious, porcelain tiled shower area with frameless door, quartz countertop, full-size porcelain toilet. The closet is the width of the coach, allowing for all the clothing storage you could ask for. Of course, when laundry needs do arise, a washer and dryer are on-board as well.
With 3 interior TVs, Direct TV satellite and Sirius Radio antennas on board, and an absolutely excellent sounding Bose home theater, all your AV needs are met within this Entegra Cornerstone coach as well. Housekeeping is made easy with the central vacuum in the coach, as well. No stone is left unturned, friend. Lastly, touchpad controls for lighting, HVAC, and AV are easy to learn and understand, too. The entire unit is incredibly user-friendly.
Outside the coach, additional storage is made easy with sliding beds that can be accessed from both sides of the coach. Additional food, tools, and outdoor entertainment items can all be easily stowed and accessed. Notice the additional Samsung TV behind the exterior panel, too! Conveniently placed under one of the exterior awnings, the large outdoor TV makes watching sports or a movie with guests easy and enjoyable! Don't want to head inside for a beverage? Yes, there's a fully adjustable, outdoor refrigerated cooler, too.
Access to mechanicals is made easy with the Entegra Cornerstone. Notice in the photos that all electric, water, and sewer connections are conveniently laid out. While parked, the QUIET on-board Onan diesel generator will keep everything up and running.
Finally, the cockpit area of this coach allows for comfortable driving for extended periods of time. Everything is laid out in an organized, logical manner, and like the indoor controls, the cockpit touch screens are easy to navigate. The air-cooled, heated, power-controlled front seats are sincerely like sitting on a cloud. The JBL sound system offers quality volume that always puts smiles on faces.
The ATC Stacker Trailer
The 2nd half of this phenomenal combination being offered is a custom painted to match (not a wrap or decals) 26' 2020 ATC Quest stacker trailer. Known for their superior quality, ATC makes incredibly strong, durable trailers, while keeping unit weight as low as possible. Dry, this trailer weighs around 7,500 lbs.
With an interior height of just over 11', folks have a lot of flexibility with the ability to haul two full size cars, or even a car and SUV if the combined heights work out. With total cargo capacity of over 12,400 lbs. and 6,000 lbs. on the raised lift, endless combinations will work while traveling with additional vehicles. Note that the floor-mounted D-rings allow for quick connections, and ample lighting serves as a welcomed guide when strapping down in the dark. The side-mounted ladder and attic allows for quick access upstairs to check straps, enter a vehicle, etc. There are multiple 120V plugs around the unit for any additional needs, too. Secure storage cabinets are available throughout the trailer, again allowing folks to keep any additional items on hand. This is a top of the line trailer that now retails for nearly $90,000 new.
Outside, the owner wanted to make sure the Entegra Cornerstone coach and ATC Quest stacker were a matched pair, so the trailer was custom painted to match the Cayenne paint scheme of the coach. Simply said, it's an absolutely STUNNING combination that looks classy for any event.
Final Thoughts
To say we're impressed with this coach & trailer combo is a complete understatement. For folks looking to travel shorter distances, or across the continent, this setup allows you to do so in total class. The top-tier Cornerstone coach allows for luxurious travel, with a reliable, exceedingly capable drivetrain. You'll be hitting the road in confidence, friends.
