  • SUIT YOUR NEEDS: With a standard-size connection valve, this large 40LB tank will connect as easily as smaller tanks, and work with RVs or trailers, propane tank attachable heaters, and other accessories.

    • Nice tank
Style: 40 LB Tank
I bought it to have a spare and paid the same price as I did for a used one locally that doesn't look as good. So it was well worth the price.

    • Seemed to be priced within 10% or so of a used one. Go figure??
Style: 40 LB Tank
I did the Facebook/Marketplace and Craigslist ads for a used one. So after a few weeks of looking for a reasonable deal, I gave up. Amazon's price on this (and I bought a smaller one as well) was within 10 or 15% more than some beat-up used hand-me-down. Your experience may vary. :) Anyway, works well, looks good and is 100% as well built as any other tank I've ever owned. ... show more
