Battery Isolator

Seems it would work, but lots of paralleling going on on the heavy gauge buss as opposed to with a combiner over isolator is only 10 gauge. I see no
downside to the isolator as the V sense is after the loss. Only a slight bit of heat is waisted. Not sure I like the delay feature as I switch to 12V
refer going down the road and that draws from house side.

From reading the website, this appears to be a combiner in one direction only. The primary (chassis) battery is the source of the charge and combine
voltage. It does not appear to sense charging voltage on the secondary (house) battery for charging from the shore power back to the chassis battery.
I does have a Boost function, but that is only for one minute for boosting when the chassis battery is low.

Just from my reading.

My Staff says I never listen to them, or something like that
 
It's written in a confusing manner, but I think it boils down to being nice
high current combiner. They say it only combines when the PRIMARY battery
is charged to 13.2VDC, which to me meant when the Chassis battery is
charged. But then they state "Allows bi-directional charging from
alternator or from shore/campground power charger/converter when
available.", which makes me think that whichever battery is being charged
is what they consider PRIMARY -- making it a conventional bidirectional
combiner.

Not a bad price for a 200A combiner: $96.59 @:

There's also an 85A version: $68.03 @:

This is the part that most class C SOBs use so they don't have to mess with the wiring in the truck chassis and get into a warranty pissing match.
They are not noted for being a reliable part (maybe not Littlefuse parts) but I don't recall a manufacturer's other than Cole-Hearse.

Matt,

Littlefuse IS Cole-Hersee. In fact most ads don't even mention Littlefuse.
