I haul 2 14' wilderness systems pungos up top. For one I use a hully rollers in the back and a mako in the front. For the other side I use hull raisers. No real reason I use two different types other then I had the rollers sitting around and when I needed the second set up I bought the hull raiser.

Both are pretty easy to load, depending on your height. I'm 5' 10" and I can easily roll the yak onto the truck using the hully rollers without hitting the back of the truck. The hull raisers are a little harder and at my height I have to stretch a little bit to lift it on.
If you do not have the factory cross bars you will need to buy mounts and cross bars. They do sell locks to lock the rack to your truck (it disconnects VERY easily and would be easy to steal), but I just snap the racks off and throw them in the back while I have the kayaks out.

Another option is the Hullavator by thule

This has gotten mixed reviews, but my wife can not load the kayaks on the truck by herself due to the height. If this works as advertised, it should help her if she wants to solo.
I'll see about getting some pics the next time we go kayaking.
Good Luck
