I have a 1998 Alpenlite Odessa 9 and am trying to find out what size black and grey water tanks I have. There is a label on body of the camper that tells me the water tank is 33 gallons but can't find any info on the other tank sizes. I have all the original owner manuals and information from the original owner but no info in those. Anyone have an idea? Anyone with a similar year?
We sold ours 8 years ago. I think I recall that the gray and black tanks TOTALED the same as the fresh water: about 15 gallons gray water and 18 gallons black water.
I agree with the prior suggestion to pour water from buckets to measure capacity. I would recommend 2 gallon buckets --- easier to lift and maneuver in a tight space.
