1994 Fleetwood holding tanks

[94fleetwood]

I recently got I believe a Fleetwood Terry Taurus model 29l? If there's such a thing? Year 1994. From a guy who didn't have time to fix a leak in the roof, all fixed up now I am turning my attention to get the rest of the trailer up and running my next priority was water, I have quickly realised unlike other trailers/rv's I have seen there is no control switch for a water pump. I did a quick search under the couch, kitchen counter shower and a few cupboards and have found no water pump either. I also only see one tank protruding from the plastic I presume is holding the insulation for a insulated floor? So is it possible this trailer didn't come with a grey water tank or freshwater? Am I missing something? I would think with the brochures saying "self contained" and it having a toilet it should have a water tank?
