Welcome to the forum
Have you looked at the Mercedes Benz Chassis Class C motor Homes. I have a 2018 Thor Siesta 24SS. It has 2 slide outs. It runs on diesel and I have the optional 3200 Diesel generator that runs off of the vehicle fuel tank. I have (2) solar panels on the roof to keep the house batteries charged. I don't do much boon docking with it. It drives like a large van and is easy to go into any National Park or campsite. It has enough power to climb with the torque that it produces. The vehicle holds 26 gallons of fuel and is currently getting 13-15 mpg depending if I keep it down around 65. The front seats provide ample leg room.
Paul
