Very interesting development. TM has learned a lot from their long experience with the folding models, incorporating good things and eliminating or modifying problematic ones. I am particularly impressed that the TM16 has a DRY BATH, as well as a permanently made up bed. Both of those are unheard of in a small upright, and a wet bath or a Murphy bed would be a complete turn-off for me. I think the floor plan is actually pretty good, too, although obviously not spacious.
The preliminary specs say "35 gallon black and gray holding tank". I think it is against code (and common sense) to have a single tank serve both purposes, and I doubt that it has two 35-gallon tanks. So I am thinking this is probably a simple typo, and was supposed to say "xx gallon black tank and 35 gallon gray tank". Don't know for sure.
To me, the bigger issue is that it is TM's move into an RV niche that has suddenly become very popular. The Foldable market may be limited, but a lot of small upright camper manufacturers have learned important lessons from foldable TMs. I am glad to see that TM is staying in the small camper pack with the TM16. I fully expect (but have no info) that the TM16 will be a learning tool, and that TM will introduce somewhat larger versions if it is successful.
