1978 GMC 26 Royale Motorhome
Unlike other GMC coaches on the market, this renovated motor home has a bright and white interior, making the inside as modern as the sleek exterior. The Bounds Co-Op Renovation replaced dried and cracked panels and seals, ensuring a weather-proof canvas for the interior update. Most of the appliances or mechanical system have been upgraded beyond OEM specs. We have had many fantastic journeys but it is time for a new custodian of this magnificent coach.
