So this seems like a basic question, but I'll ask anyway because I've seen varying answers. Our new trailer has one 20# propane tank. It generally looks just like a tank at your local Menards you ca...
Here's some truth without the flailing arms. I'll never notice the difference as a 20 (15) lb tank lasts me a couple of years at least with our WeberQ 120. I have three so running out isn't a concern. I refill my 30 lb tanks at U-Haul about one every six months. This works and will continue to work for me. The convenience is worth the imperceptible difference in overall cost.
