Capacity-Galley Tank?

[barmar]

Need to know the capacity/volume of the galley grey water tank in my 2007 3400RL. The total capacity for the two tanks-galley and shower/sink-is 76 USG. Are the two tanks the same size so each at 38 USG, or are they different?

Unless someone really knows ... get a 5 gal bucket and start pouring until it's full while keeping track of how many buckets. You'd think for commonality of build they'd be the same size, but my gally tanks have always filled up seemingly quicker than my main grey tank.

They should be equal size at approximately 38 gallons.

We had the same year and model. As Jim said ours was 38 gallons.
