S&S camper lacks grey tank

I recently bought a 2003 S&S 9 SCS with some water damage. I am in the process of rebuilding it. I love the camper and am amazed at the build quality compared to my old coachman truck camper and previous toy hauler. However I noticed it only has one drain valve at the back, and it appears all the fixtures drain straight into the black tank, looking in the basement and following the plumbing. I cannot find any drain valves anywhere, and see only one long tank in the basement on the left hand side, with the 2nd space where another tank would fit being empty storage space.

This is concerning as I do a good bit of boondocking. It reads 30 gal, which won’t last long with everything draining into it. I can bring a tote but annoying to have to smell black water all the time. Looking like I’ll have to add a grey tank.

I didn’t think it was even legal to lack a grey tank on a modern rv, and with the quality of everything else it surprises me. It looks factory plumbing wise, doesn’t appear rigged or anything.

Does anyone know if this is common in these campers/have experience with this? Can’t find much information online regarding the plumbing of s&s campers, any help would be appreciated. Thanks in advance.
  • Did you try to contact manufacturer for the manual?
    Maybe fellow forum member owns same camper model, to give you direct advise, but TC don't have any building codes to observe, so everything is possible.
    Bad news - gray water in black tank makes black water.
