So, we have just returned from our first long haul trip from Colorado to Florida and back, a total of 4200 miles including a stop in Davenport, Iowa, in our "new to us" 2004 Pace Arrow 37C, pulling a Dodge minivan on a dolly.
As per our signature I did install the Ultra RV TCM and ECM units, and new Bilsteins prior to the trip. I'm happy with the performance of the coach, in that as hard as I tried to keep her at 62 - 65, she likes to creep up to 70, and seems to be quite comfortable at that speed. I don't.
On long pulls and brisk head winds coming across Texas, I hear the engine fan roaring quite a bit, and it does not take much for her to downshift. When she does, I immediately lift off the gas and try to keep the revs below 3K. This results in a speed drop to 55, and I have to wait for the next downgrade to get her back up to 60+ and in 5th gear.
So, my question is, there are 2 "pancake" fans in front of the air conditioning coils. What turns them on ? AND is it possible to put an indicating light on the dash to tell me when they are running, AND has anyone ever wired them up to a switch on the dash to control them manually.
This would seem to be a benefit in high heat / load / traffic conditions.
And maybe cut down on the engine fan roaring at the slightest sign of a hill.
Anybody traveled this road before ? I would welcome your ideas.
