Holding Tank Size
The owner's manual for my 1995 29.5 states the holding tank size is 20 gallons. I have no idea if that is, in fact, the actual size or not. I think it's close to that based on my experience the past 6 years with it. Anything smaller would be a problem in my view. I would think the 1994 model would be about the same size,but don't know for sure.
