In the past 10 years of GMC operation we have found through our
experiences that operating the roof air with the Gen Set is obviously
more practical for us! Going to Reno up Hwy 80 or to Las Vegas on 15 or
between SF and LA you pull some pretty heavy grades. When and if you
are using the engine compressor you are taxing the engine more. If you
are on flat ground it would be no problem. But even in our automobile
we turn off the air conditioning once we hit the hills! I have seen
"Warning Sign's" advising the drivers to turn off the air conditioner on
some of these grades too! We were really lucky on more than one
occasion too. We were driving along with the roof air going, it was 120
degree temperatures, cars were stopped along the road steaming from the
radiators, over heated. We just kept going (slowly) up these grades.
The Caspro Gears in the Transmission and the Final drive allowed us to
go up at 45 MPH and in some places we down shifted as advised but other
than that we managed to pull the grades with no noticeable problem.
Strongly recommend "Not To Use The Dash Air " on hills. Chuck
