Argosy holding tanks

[SmokelessJoe]

Andy Thompson of Can Am explains the fact that current Airstreams have about 4 times the holding tank capacity of old Argosys this way:


“The reason tanks are larger now is that they are mounted close to the
axles which allows two things. The tanks can be much deeper because
ground clearance is not as big a concern by the axles. The other reason
is the weight does not matter next to the axles
either. As well the frame rails are 6" further apart which leaves more
room for the tanks.”

Has any one out there installed new, bigger tanks in an Argosy? Maybe moving the grey to the axles and using the space at the front for a bigger black?
