Hello Bill and welcome from Virginia. I have a 2014 R3T (Touring not the Tourer) and have loved it these 47K miles it has given me. Mine does have ABS and is the first out of 28 bikes I have ridden that does. I am sold on it and have used it twice now at freeway speeds to safely help avoid mishaps directly in front of me that left me no escape route.
The only upgrades I have done to mine is add on the TORs exhaust and a new tune. The stock power is great, I just didn't like the sewing machine exhaust note. I gained a few ponies when I did the upgrade but it wasn't significant. The power it has stock is far better than your current ride. When I went shopping for the Rocket, the Roadking was on the top of my list. But riding them back to back along with the Thunderbird, the Rocket came out on top and the RK fell to third, based on my requirements. (I still hold the RK as one of my favorite Harleys though).
Once you ride it the R#, you too will be addicted.
