re -- uneven distribution
Based on my experience, I am amazed at the enthusiasm of expanding spray-foam insulation.
It expands to fill, nothing stands a chance after it gets up a good head o' steam.

re -- voids
I tap to locate unfilled areas.
A new hole drilled, a quick squirt, and that seems to be the ticket.

re -- remove batting
I think removing insulation so I can add insulation is... counter-productive.

On our rig, part of the insulation 'package' is our photovoltaic system above the roof.
(On a stand-still house, eaves can contribute to slowing the air-change against the exterior walls.)

I think of the entire vehicle as a holistic environment.
I think parts of systems need to contribute to that complete system, just as all the systems flow symbiotically.

A home-built rig can be simpler, because we do not need to park it on the revolving pedestal at the dealer, impressing tire-kickers with fancy decals, chandeliers, or frighteningly-complex electric systems.
Or holes in the roof [spit].
