This motorhome has an 8.1L GMC engine, a 5-speed Allison transmission, and a Workhorse chassis. It was an RV show model, so it has many upgrades. It has 2 slides which makes plenty of room in the kitchen/dining area.Trek motorhomes have a Magic bed that lowers from the ceiling in the living room, so you have the same amount of living space as a 40 foot motorhome. No separate bedroom and a spacious bathroom.We have loved this Trek, but health forces sale. New tires and house batteries purchased 2 years ago. We added 450 watts of solar panels and installed a 2000 watt Xantrex inverter in January 2023. It has a newer flat screen tv, improved exhaust system, and improved suspension/anti-sway system.
