It depends on what you plan to do with it. If you're going to own it a long time, and you can get it at a good price, knowing that a salvage title does impact the value of the vehicle, you don't have much more to worry about than any other used vehicle purchase. Seems fishy to me it was totaled for needing to be replumbed and new tanks. Make sure any work was done correctly, get it inspected if possible.
Next thing, call your insurance company and make sure they'll insure it. That might be the biggest wrinkle you'll encounter.
