AIR SYSTEM ??

[Don Bradner]

I really don't know how long it takes to air my coach up with the engine because
I never do it that way. My startup procedure involves using both block heater
and aux air pump from the time I get up on any morning I'm going to travel -
that way I can just start and almost immediately roll.
