According to the manufacturer's website, there is a 28 gal. black tank and a 39 gal. grey tank.

All black tanks in that model line are listed as 28 gal. Only 4 of 15 models show a grey tank larger than 39 gal. If there were truly 4 tanks, I'd expect to see 4 dump handles.
That logic sounds correct.
