I'm curious how well it (redarc elite model) works and your opinion of it. I've got the red boxed liberty model to install this week before picking up an equipment trailer.
The Redarc worked well, once I got it dialed in. The initial setting of 5, recommended in the manual, was a bit too low, so I tried various settings and found 7 to be just about right. And it's nice not having to reach down by my knee to adjust it or to activate the trailer brakes independently.
You may notice the void in the dash where I removed the factory radio, and have yet to install the aftermarket head unit. I really should do something about that.

Hope the trip is a painless enjoyable ride. Pretty area down there. If you want an easy way to see the atmospheric pressure difference, take a sealed bag of chips from the valley up onto Mt. Rogers and note how 'full' it appears at elevation.
Thanks. It is s a beautiful area. Getting to it is a bear, though, particularly through the last stretch of Hwy 58, and then the road into the park. It's pretty steep, and there is a three mile section of 15 mph curves that are just about at the limit (at least in my experience) of towing a 24' camper with a 19' vehicle. Fortunately we didn't meet any large vehicles coming the other way through that stretch.
And yes, we had some pretty well-inflated snack bags when we got to the campground, which I believe is a little over 4000' elevation. We did a fair amount of hiking; the altitude was definitely a factor.
The Subdivision did its job, but had to really work hard over those last few miles. The coolant temp got up to 245º, and the transmission temperature got up to 254º. There was nowhere to pull off and let it cool, so we just kept going to the campground. The temps started dropping as soon as we crested the last hill.
I was afraid I had cooked the transmission, but I looked at and sniffed the transmission fluid, and it was still nice and pink and didn't smell burnt. Plus, after reading the GM Service Manual, was relieved to find that it doesn't generate a code until the temp reaches 277º. Just to be sure, I checked it this morning with my scan tool, and found no codes.
Except for the above, the TFT stayed mostly around 212º, and coolant stayed between 200º and 220º. So now I have baseline values, and what I hope are maximum temperatures for coolant and transmission, under normal and adverse towing conditions at around 85º air temp.
Now to install the new fan and clutch, blow some compressed air through the cooling stack (once my compressor is fixed), and do a drain and flush of the cooling system.
Our next trip is on July 29, to Douthat State Park, and I'd like to have all that done before the trip. We shall see.
