I'm wondering if two non-compact 2-dimensional manifolds are homeomorphic. The first is the "loch ness monster" a one ended surface formed from the sum of infinitely many tori:

The other is a surface which I do not know a name for but is related to the "mucube" (a polytope) and so for want of a proper name I am simply calling it that. One way to construct the mucube is to take the tesselation of 3D space by cubes, select all those cubes with at least 2 even coordinates, and then taking the boundary of that set.
Here's a section:

Both of these surfaces are orientable, one-ended, and have infinite genus, so it seems like they might be homeomorphic. I don't have much experience in this type non-compact topology, so I've exhausted all ways I know to tell two surfaces apart. I also can't construct an explicit homeomorphism between the two.
Are they homeomorphic?
