How critical is it to have a perfectly level trailer?

Moving the battery to the rear was mentioned. If you do this it needs to be connected to the electrical system so that the brake a way can function in case the trailer separates from the yow vehicle.

Thank you, I didn't think about that. Someone already pointed out to me that I will actually be within my limits even with a propane tank and a battery. If need be, I'll just put something heavy in the back of the trailer.
