Our 26' GMC Royale with Rear bath is arguably one of the finest GMC Motorhomes on the road.


Approximately 13,000 were built and we have had this vehicle inspected by Club Members and their consensus is that none have been thoroughly restored to his standard.


The previous owner was a very successful man in the Publication industry and he spared no expense what so ever. It was a dream of his to have one of the very best GMC Motorhomes in existence, and he contracted Cinnabar to perform a full restoration of this vehicle. Over $110,000 dollars was spent it took two years and the vehicle came out spectacular. Used all OEM parts and proper installation of all components by the pros who bought the Plans from GMC.


If you are looking for a GMC motor home this is the one to own. We purchased the vehicle last year from the gentleman who contracted all the work done. Unfortunately he never really used the motorhome the kids had grown up and moved out, his books were on hold and he couldnt find the time to travel. The vehicle was in mint condition and stored in a enclosed structure everything looked brand new and everything worked. The vehicle is fully loaded and includes a modern Audio and Video system with Satellite Direct TV we added blue Leds for ambient lighting.


Below is a list of upgrades and repairs a full file of receipts from Cinnabar will accompany the vehicle noting much of these components. Every detail was addressed and there is too much to list the vehicle is simply brand new in every way and arguably The Absolute Very Best. We had driven it 800 miles on the first trip and have enjoyed it locally since, you will not find a finer example and if you are looking for the finest in GMC Home Motoring this vehicle is flawless.





This coach was totally reconditioned by Cinnabar Engineering. With care, it should easily last another 25 years. Cinnabar Engineering purchased the manufacturing rights to the GMC Motor Home and offers a complete line of parts and services for proper maintenance of the coach.
