Sluggish towing with GMC Yukon
I just picked up a used 2007 Jayco Exp 17C & towed it home last night with my 2011 GMC Yukon SLT. The drive was 2 hrs & lots of hills in TN. I had the tow mode on. It seemed to struggle up the big hil...

I believe Platinums only come in 4wd and only come with 3.357:1 final gear ratio...guessing that equates to 3.36. How do I tell if it has a HD tow package (like extra tranny cooler). Sorry dad didn't teach his daughter much about cars. I read it has autoleveling suspension. I assume that will take care of any rear sag? What kind of gas mileage towing do you get?
If the Armada has the autoleveling suspension and the 3.36 gearing, you will have the HD tow package. You probably already know this, but it is even pre-wired for the trailer-brake controller and has the 7-pin connector. All you need is a pigtail between the connector located under the front dash and the brake controller of your choice and you are good to go.
The autoleveling suspension will take out any sag, but make sure to still have your weight-distribution hitch setup correctly. Also, when hooking up your trailer, hook it all up, including the WD hitch, when the Armada is off. Once everything is ready to go, turn the Armada on and let it auto-level. That is the best way to do it to get the correct weight distibution.
As for gas mileage...I saw as good at 12mpgs and as bad a 8mpg, average was 10mpgs with the Armada. With my Titan that has the stock 20" tires, BDGT and intake, I see a consistant 10mpgs. That is with all the hills here in CO.
