The one that Keystone provides is sold under the Dometic name and can probably be ordered through Camping World or other RV parts places. It appears identical to the InterVac Designs unit shown on this website (except ours is black).

So far as where to put it, I don't know where they would go in a new 3400. In our '05 3670 there is a blank space under the closet by the entry door next to the breaker panel, but I think the 3400s are different now. Our installation is similar to the one on the right on the website.
Anyway, we got the Dometic version installed at the factory for probably too many $$$, but it works well and fits neatly into the space provided for it in our unit. We built a storage drawer for the tools under our oven. Maybe someone else will have other options to offer, but we like the one we have.
