Try riding the different models at one or several of the dealers in your area. That would be the easiest way to find out what fits your needs and style of riding.
Riding a Roadking does not determine that you have a touring motorcycle.
I would agree with going to a dealer and figuring out for yourself what you want. Most are a pretty multi-purpose bike, there is no reason why you can't take a an Electra Glide or Road King around town, or why you can't take a Fat Boy across country. There are a few who will put a lot of miles on a Sportster.
