Why do they take it out? Makes me want to take them to the slapping
room! When I bought that coach, one year old, the box was gone.
Since this was before internet, it took me almost 3 months of
writing and calling various manufacturers but I duplicated
everything that originally came in the box and bought blueprints
from Blue Bird along with owners and parts manuals.

Sporlan valve in the heater plumbing at the back, while Blue Thunder
does. Is that something you did?

No, I didn't add that. The only thing I changed in the engine
compartment was to replace the original (no longer available) vent
blower to exhaust engine heat after parking. I made a duct the size
of the original blower and powered it with a flex duct and a bilge
blower.
