What's the longest you have run the trailer for without having to fill up on more water or gas for the generator?
Water unknown had a unique situation where I did not really use water in the trailer, had a bathroom on site, and did dishes elsewhere. Generator I would fill after each use, but never had a day I needed more gas. I would say probably 2 - 8 hour days
