It's OK! It's the research that will make you confident driving down the road. Those who don't do their research end up making poor decisions. As far as brand, I can recommend the Equal-I-zer brand sway control WDH kit. My camper is around 750 lbs TW, and I use the 1000 lb kit (fantastic ride).
You have 1960lbs of CCC, but you'll never use it (unless this were a toy hauler). A good conservative estimate for options and cargo weight, is 1000 lbs over dry weight. That puts you at about 6800 lbs estimated loaded weight. Comfortably within your 9300 lbs max towing weight.
TW should be 10-15% of loaded trailer weight. 15% would be is 1020 lbs, right at the limit of a 1000 lbs WDH. Feedback has shown that having a TW too close to the max rating of a WDH can result in bouncy "porpoising", where the spring bars act too much like springs, and not enough like rigid bars. So, I like to add 100 lbs to my estimate (1120), then round up to the next rating. This puts you using a 1200 lbs WDH kit. I just checked a calculator on Equal-I-zer's site. 6800 lbs with 1020 TW calls for the 1200lbs kit, and is good for 0-300 lbs of payload in the bed of your truck (behind the rear axle).
If your trailer came in at the more typical 12.5% (850 lbs), it looks like the 1000 lb kit would work as long as you don't put very much in the bed of the truck. I would hate to go small, and regret it. If it doubt, standard recommendation is to err on the high side.
I recommend you contact Equalizer Tech Service. Tell them you aren't sure where the TW will come in, but should be between 850-1120 lbs. I'm sure they will easily recommend the 1200 lbs kit.
