Only good is they keep gas in tank. My tank has a broken gauge,, was delivered that way. Delivery drivers always complain about it, like it is my fault. Several have not put gas in tank because of this. Several have said that they would see that it was fixed. We have complained about this problem, and so far no one has done anything about it.
Come without too many calls in the last 22 years. We have the same tank and have asked several times to get it level without this job being taken care of. otherwise very nice drivers and no other issues.
They seem to be pretty prompt with their service to our tank. I do not recommend their products that they sale at their store. They would not replace and appliance I purchased from them with a lifetime warranty and it broke after five years.
