there is also the fact they have to stratigicly plan where stuff goes to maintain a spicif center of gravity. for example the one thing I do not like about this camper is that they put the batteries at the front so you have no access when loaded. I am going to cut out the abs battery box since I have LiFePO4 anyways, then I can just unscrew the step into the bed to gain access from inside the camper. it will also let me insualte the harch and have heat to the area so I don't have to worry about cold weather camping.
