Yeah I ended up buying a teardrop trailer last August. The problem with just sleeping in the car or setting up a tent next to the car is the lack of storage. I'm gonna be living on the road full time so I need more stuff like a stove and a fridge and clothes and dog stuff. It adds up quick and the trailer is the perfect solution I'm happy with it.come on man with the back seats folded down its like a queen side bed back there in the model s, with better then home cooling and heating why would you even look at camping on the roof
