I am a Northern Tool dealer thru my RV dealership. I ordered 4 of the tanks you are talking about. All 4 came in scratched and damaged by Yellow Freight. I am still trying to settle with Northern and Yellow. The tanks themselves are good. I installed one of the 90 gallon units in my truck and love it. Here is where they get you hooked. The tank (90) was $469, then the shipping was $125 and then after you get the tank, you ask how does it hook up? Oh, you wanted to hook it up? We have the hook up kit for $249 plus shipping. Soooo, add all the numbers and go from there. Would I do it again? Probably not. We have several after market mfg. in our area that will install a similar unit for around $1100. Oh, I also paid $100 to have the hook up kit installed. So, the total is $943. For a few $ more and a lot less hassle, I could have had a unit installed a lot faster. Northern/RDS took a month to get the tanks to me. That's my story, yours may be differant. If memory serves me, RDS is in Perry, Fla. How far is that from you???????
