We have a FC 20FB, I have a
1500 Sierra, I think they pair well. I find the pickup useful as my daily driver (trips to Lowes, moving the kid into the dorm, etc.), but handles towing chores really well. I also like the way you can install TPMS into the camper wheels and check the temperature/pressure of the tires while rolling down the road, tap the camera button to zoom in on the hitch when backing up, just lots of little things about a truck that are handy when camping (can bring along an extra chair or two if needed, or a solo stove, store a dirty campsite rug so you can get it home and clean it up, etc.).
We do use a BlueOx Swaypro. It works well for us. Other people like their EAZ, or a Equalizer, etc.; I've never used any of them, but they each have their supporters.
