Thank you, @RAY & DONNA. We've owned an outland portable fire pit for a while.
I carry an extra 20# propane tank so I can place the fire pit wherever we wish without going to the trouble of removing our third tongue-mounted bottle for that purpose, but that 4th tank is duplicate extra weight.
Even though I figure our 3/4 ton TV can handle whatever I choose to carry I should use some discretion. Hose ordered.
