What kind of freshwater tank?

[photomikey2]

I am coming up on some free time this summer, and I'm revisiting the idea of removing the galvanized water tank and replacing it with a plastic tank. This will also include removing the pressurized air pump and installing a demand water pump.

First step is the tank. A few years ago I'd spec'd out a water tank from Plastic Mart in the 40 gallon range, about $350:

Now I'm seeing lots of tanks that would work for me from an RV supplier, in the $90 range.

Is there any difference between the two (other than $250?).

And... where is RV parts nation getting their tanks from? I'd rather order from the supplier than add a middle man and two weeks.

Thank you!

I found a freshwater tank that suited my needs at the local RV repair shop, it was approximately the same price of having one shipped and I was able to ask lots of questions and get advice about installing it. It turned out to be a tank from ICON and works perfectly.
