My state DNR has levied a requirement on me to have a minimum 300 gallon water tank (mobile) to accomplish some activities that I need to do. I have been trying to figure out how to do it at minimum cost and thus hope to re-purpose an older trailer as the water wagon. The trailer I am looking at is not large but the concern is the axle rating. How do you determine the axle rating on an older trailer (this one happens to be from a SA-200 welder thus my concern) Is there a stamp on the axle somewhere with that information? If I turn my equipment trailer into the water wagon then I can't move the other equipment that is normally transported on it and I would like to make this a permanent fixture that I do not have to remove and reinstall.
Tank will be a horizontal leg tank 36" diameter and 68" long.
