Mounting a roof rack to the penthouse top

[SierraHawk]

I have a low profile roof rack that I want to install on my PH top.

Should I drill through the roof and put a nut on the inside or can I screw the rails directly to the plywood ridges?

Are there any suggestions as to what kind of screw or well nut I should use?

Anyone know how thick the plywood strips on the PH roof are?

If you decide to go with the rails, be sure to install them in a way that the holes you drill are "outside" of the canvas. That way if the holes leak for any reason, it wont leak to the interior.

I just got all set to install a rack on mine, for a large thule cargo box. That's about 57 lbs of weight, so I put two barbell weights on the top to try it out. Not only was it harder to put up, I didn't like the wobbliness of the top.

I took the wrights down and laid the cargo box and bars up on top, and still did not like the way things felt up there.

I know that there are threads about tightening the PH springs to make raising the top easier, but in the end I decided it was not worth it. Taking the bars and raingutter mounts and such back to REI.
