I also purchased a smaller propane tank to use with it...an 11 pounder I believe it is. Even tapping into the regular trailer tank would have meant a longer, but still limited, run of hose.
I had a low pressure connection on a previous trailer, and found I just didn't like it...too limiting on what you can hook up without modifying something.
