Replace Roof AC units - 1992 WB40

[Pete Masterson]

My inside covers are plastic -- and the screws holding them are
reachable inside after you remove the 'return' screen.

While the Dometic Penguins are low profile (and probably exact
replacements for what you currently have) you might consider the
Dometic Brisk-air "High Efficiency" units. I replaced 2 of my 3
Penguins with these units. They only draw 10 amps (each) instead of
the 15 amps of the Penguins. The Dometic brand will work (usually)
work with the Dometic thermostats (if you have that arrangement) and
simplify the wiring necessary.

The downside is that the Brisk-Air units are several inches taller,
costing you some clearance. On my coach, the King Dome is already
taller -- so the Brisk-Air units didn't really affect my clearance
anyway...

The high efficiency units are slightly more expensive than the
"normal" units -- but you may appreciate being able to run them when
available current is limited -- it just gives you that much more
margin when using a 30 amp connection, etc.
