Kayak racks

I have been researching TT for some time now and I am very interested in in the TM. This is a great site and I have enjoyed reading the messages and learned a lot. Does anyone have any information on installing kayak racks on top of a TM. I called the factory and they said it can and has been done, but not from the factory. I am looking for an easier way to transport my sea kayaks (set of two- 13 ft/ 50 lbs.). I currently use a Yakima set up on top of my Landcruiser, but it a pain to get them up there even with two people. The thought of drilling holes into the roof of a new $30,000 TM makes me cringe. Any suggestions? Also, I live in Northeast Florida so if you know of a newer/used TM for sale, let me know. I like the 2720sl and 3124ks(big money) but mainly looking for a good deal. Thx for your time.
