04 28 safari 70 gallon combined black and gray tank

I guess we own a unique bird, 04 28 safari with combination tanks. I have owned over 5 rvs before, so this took some getting used to. Any of you history buffs know what was the reason for the change? I find for my kind of travel, I can let it fill and fully flush, so it work great for us. It must not be popular however as no new unit offers it. Just intrested in comments.

That's a new one on me. I thought that the 16' Bambi was the only Airstream with a black/gray combo tank in recent years.

well its good to see they offer it on other models. This is over 70 gallons combined. I crawled under the coach and the tank is huge. It always fully drains and cleans so I wonder why it was only our model? I wan not sure about it at first but it works great.

There were seperate tanks on the 28 and then one year, they built it with a combined tank and there was such a firestorm of folks upset with that, I believe the switched it back to seperate tanks. I am not sure on the actual year they did it, but it was fairly recent in terms of model years. Currently I believe these to be now two seperate tanks.

Our 2007 27FB Safari has separate tanks but I sure wish they were combined. With 2 teenage daughters we always fill the gray tank long before the black tank. It sure would be handy to move some of the gray water to the black tank. I wonder if a retrofit is possible.

hi '28...

fair number of threads on this issue of the combo holding tank.

here are just a few....

i would NOT want that set up but i'm sure it works for some...

no sneaky dumping while boondocking please!

all of the true things that i am about to tell you are shameless lies. l.b.j.

we are here on earth to fart around. don't let anybody tell you any different. k.v.

I admit with previous rvs I was guilty as charged fo dumping grey if I could get away with it. Our travel is usually into a park, and just last night getting in late my 70 gallon combo tank was empty, we had 2 showers at night, 2 more in the morning, misc use and i checked the level and less than half full. I never messed with the dump. I can tell you when I do empty it is a flood and the tank always seems clean. The tank is mounted just aft of the rear axle, and when boondocking it is really nice, I find little change in the unit sway when it is say half full.

I understand why some would not like it, but airstream should have it as an option for those that want large capacity combination tanks and willing to never, I mean never be what I used to be. A ghost gray water dumper. That being said, this is a good idea that needs to be explored.
