Product review (1 stars): Poor quality! Poor packaging!
Ordered 1st tank for my husband. It came with the burner end bent in. Rather than fix it, I emailed Amazon who replaced it. I opened the box and the 2nd one was worse yet. The boxes had nothing in them to protect the tanks. My husband, being a pretty good fabricator he said, "OK, I need to get this thing in". He machined a piece of aluminum on a taper to go in and push the tube out. That was OK. One exception, the tube going in and out of the tanks are not round and look like they were cut with an ax. We attempted to put on the steel retaining rings which had about a .070 crush to them. After reading some posts he made another piece that tapered up to the 2.500 tube size and another to slide over both and tap it on. GOOD LUCK!! As it hit the tube on the tank it just tore into the tube. By time he repaired the tube again, the aluminum became soft. Again, the tubes were not close to being round and he gave up. Then we called 2 large RV places that both told us they will not replace just the tank for that same reason. They say the hours they charge to do it are twice what it takes to just change the whole thing. We called Atwood who told me they use special fixtures for replacing the tanks. For those of you who had success doing this. I applaud you or you are blessed!
