Onsite camping works as follows:
If you are on the back row because your trailer is over 25', then there is usually room for a camper or motorhome as well. If your car is on paddock rows 2 or 3, then you will either have your under 25' trailer in the space with your car, or your under 25' camper or motorhome and no trailer in the space. If you are in row 1 or you cannot have your camper or motorhome in the paddock space, there is plenty of room East of the paddock and registration building. There are a number of other people camped over there every race weekend including many of our volunteers, so you will be in good company.
I'm not sure about fuel transport across the border, but as far as I know there are only restrictions on lead-based fuels.
