I finally had a chance to get over to Carli in Lake Elsinore and was able to have Dan (VP at Carli) ride (he actually drove) in my truck so I could get a professional opinion on the suspension performance.
Well, a big "issue" I had/have is the way I drive my truck. I drive like an old man and baby my truck. The kit I purchased and had installed is just not the correct kit for me. Dan took some pretty significant concrete gutters and the took absorbed those transitions pretty easily.
I had installed the timber grove airbags in the rear because I don't like how the front sits higher than the rear, so the primary issue with the test drive was the behavior of the rear of my truck. I knew that going into this and was not really a fan of having the airbags installed. I only did that because of the issue I have with how much higher the front is. Dan wasn't sure why the front was higher than the rear but I believe he thought it was more likely that my rear was lower because of my camper shell / topper. That would seem obvious to me as well but the suspension in the front was higher before I put the camper shell / topper on, so I know that wasn't the problem with the lift portion. You can see how much higher the front was in my profile picture as that is how the truck looked shortly after the initial install.
Anyway, Dan was gracious enough to provide me a solid discount on the heavy duty rear springs. I pulled the airbags out last night and will get the heavy duty springs installed as soon as I can. I will report back. I figure that change should at least get the rear level with the front and should give me back the full shock travel in the rear that I couldn't get when the airbags were installed.
I also greased the hell out of the UCAs a couple of weeks ago and that seemed to help a bit. It doesn't so much have that feeling of being on its tippy toes.
All said, I would like to amend my initial observations and say that before one buys a performance kit one needs to understand that it's intended/designed to be driven in a more performance oriented manner, not like an old man on a Sunday drive. The Fox commuter system most likely would have been the more appropriate system for me.
More to follow as I continue to get this system dialed in.
