Kayak mounting on Rv

I just purchased a new 27' Komfort Trailblaizer RV.  Anyone know a rack system to mount on the top of this Rv for a Kayak.  I have been searching the web for the past several months and have not come-up with much.  I figure whatever it is, a dealership will have to install to completely cover the roof warranty.  The only thing I have brainstormed is mounting two simple bars or mount some strong rings to the top to secure the kayak in place.  It seems a company such a Thule would have come-up with something.  Any advice would help.

Thanx,

Perhaps a trailer?
 I reconfigured a small boat trailer to carry 4 kayaks without a blink and its REALLY easy to load. Roof of an RV is a looong way up!
