Thank you.

You are looking for rectangular box tanks.
Google is your friend for a local tank supplier.
They will spin in whatever fittings you need, basically, they end up welded/melted into place exactly where you need them.
As an example, this company is in Mississauga, Ontario, I used the 49 gallon on their edge, leaves enough room under the utility bump for some insulation under and over the tanks, and I installed drains both sides.

Can't remember what they cost...
Remember, water weighs 8lbs a gallon. You'll have more water than fuel onboard!
Happy coaching!

As Buswarrior says, you need to find a local rotomolder of tanks, because trucking them could cost more than the tanks themselves. FYI, I used Ronco Plastics in Tustin CA http://ronco-plastics.com/newRonco/index.php , and to make four large tanks totaling 400 gallons cost me $2.50 per gallon, and that included spin-welding in umpteen fittings exactly where I wanted them (one tank has seven!): http://www.bunnweb.org/spinwelding.com/index2.htm

If you need an odd-size/shape you can also have custom tanks made from sheets of plastic which are 'welded' together. These end up much more expensive, but can help in a pinch when you're trying to do something that isn't available as a rotomold.

They can custom make any size tank.
