This a good shell for someone who is looking to build a Skoolie. The roof was lifted 20 inches which cost $10000 on its own. Their is 3in of insulation on the floor, walls and the ceiling. I put a lot of money into this project and then I was robbed. They stole all of the units a put inside. They also ripped out the muffler. I hooked batteries recently to make sure that the engine turns over and it does. Sadly the peddle falls to the floor. I am just trying to make some money back to get rid of the debt I earned from building this. There are 1800 watts of solar on the roof. This is good for someone who can handle a big project
