I bought an Aero, 45 gal, diamond-plate tank last April and I love it.
I looked at a lot of tanks on-line and went with Aero partly because I could drive to Corona and pick it up, saving freight costs. I bought the DP-45 and this tank has excellent welds & good construction all around. I installed it myself, plumbing a NAPA diesel filter and a selector valve into the line. I mounted a switch and a green LED in my triple gauge pod and wired it so that it will only run while the ignition is on. I use it all the time. I love it. Next to my ATS Trans upgrade, it is the second best thing I have ever done to my truck.
