If you need two 40 gal grey tanks, then contact Crossroads at the factory to verify. Why place an order with a lot of ifs and then be disappointed after waiting for delivery for several weeks, to find out it isn't what you wanted.

I just checked and your right they only show one gray tank. If you do full hookup it's no problem but for boondocking it's the pits. I'm happy I bough my camper befour they started takeing everything away.
