We bought this for our RV site and it is just what we needed. The local propane company came out and set it up with the correct regulator and pipes and it has been working as expected for over a year now. It makes life so much easier compared to when I had to change out the 30 lb bottles every few days in the winter.

I received regular communication from the shipping and scheduling team. The tank arrived in perfect condition on a pallet and they used a pallet jack to move it into my garage. The tank is heavy so you’ll need to either lay it on its side and roll it or use some other method to move it to the installation spot.

Bought this in October of 2023. Got it in December of 2023. After getting this some of the propane fill places asked how I was able to buy this take. I told them and they said nothing. I have found that because I own the tank they give me a better price. How I found out is that I heard my neighbors complain about the propane price they have to pay because they can’t shop for the best prices. Most of the time it’s $1 a gallon. Lately it’s been $2 a gallon or more.As far as rust. I found that it’s primer on it. You can get 2 rustoleum white spray cans at Home Depot for around $12 for a can.Looking at how much you save on propane cost why complain.If you are using it on your RV. You can hook it up to your RV propane regulator. You don’t need anything special.

The tank looked fine upon delivery, but when filled the valve leaked so bad that the propane company had to install a check valve to prevent all the propane from escaping. when reported to the seller they said it could be fixed with a screwdriver, dismissing the problem as insignificant. I had to contact Amazon to get them to step in to help and get the valve replaced.

The tank arrived fast, delivered in about 2 1/2 weeks. It's made in Thailand. Got mine Sep '22 for $1,175, a great deal, and after that they increased the price. Since I'm installing it near the beach, I contacted Flame King to ask about their corrosion protection, and if it would hold up. I suggested adding additional paint, and they said it was a good idea. Coated it with 1 quart, 3 coats, of 2-part PPG commercial paint ($73), Terex gray color, using a Harbor Freight HVLP gun. Good thing that I did as there were spots worn through from shipping. It arrived wrapped in plastic, one small dent, but no pallet or other protection. It's getting installed with a Rego 2-stage regulator, the brand recommended by Ferrellgas. Edit: After the initial fill, Ferrellgas refused to fill it unless it was white. Two cans of appliance white enamel from Home Depot later, they filled it.
