My trailer came with a pre-plumbed coupler on the low side of the trailer regulator for grill plug in. I unscrewed the regulator that came with the grill and had a hose made up long enough to get the grill away from the trailer, and screwed it right into the port where the grill regulator came out of. This allowed me to plug the grill directly into the trailer and grill till the cows come home. I then made up a fitting that allowed me to plug the regulator that I took out of the grill, into the long hose which I had made up, in case I wanted to plug in a standard bottle (1 lb, 20 lb, 30 lb) and take the grill farther away from the trailer. I have yet to use the reg/adapter in five years. I always plug the grill into the trailer and it works great. I even grill under the edge of the awning in the rain if necessary.
