Second grey tank

It has been stated that the newer 08 Cyclone 4012s are having a second grey tank added. Our trailer goes in for warranty work tommorrow. Can this be added to our 08 when in the shop? This has been the only disappointment with this trailer. It has been a greater hassle than I expected. Thanks Doug & Deb

Getting the 2nd grey tank in the 4012 required quite a bit of changing in the frame. Slide out rams moved to allow for the dual water tank setup, which had to happen to get the 2nd tank in there, cross members were re-located, and some new ones added. Not only would the frame change, but the water tanks, and routing of water lines, and above floor plumbing, and termination plumbing would be involved, also, running wires to the monitor panel (so you know when the tank is full). I know this doesn't answer the question of if it can be done, but I thought I would let you know the changes that were involved in making this happen at the factory.
