tank capacities

[John L Hallett <liveyr2@xxxx>]

We own a 1987 Airstream Excella and I'm trying to find someone who can 
tell me the holding capacity for the fresh water, gray water and black 
water tanks. I searched through our folders we received when we 
purchased it and can't find this information. I asked a dealer here in 
Mesa, Arizona and they didn't know. I could get a couple of five gallon 
bottles and fill each one up but that seems a little rediculous to just 
find out the capacity. Any information or leads would be appreciated. 
Thanks.

John
