Well, I did it. I finally bit the bullet. I got the Thule roof rack for my Xtra Cab. It's rated for 160 lbs. so it should do well with my boat and my bike (damn lefty fork on the bike, can't take the wheel off and stuff it in the bed under the cover). For everything to carry my bike and 'yak it came in at around $500 which isn't too bad.
I was going to go with the XSportster but with all the complaints of whistling I thought I'd try a different route. If need be (when I buy a bigger/longer boat) I can always get the goalposts for the trailer hitch and use my existing equipment on there.
And here are the pics (truck is filthy, my appologies. It's the bike's fault).
...and one of the bike that made it all happen (my other baby...next to the Taco of course).
