Re: Mounting a roof rack to the penthouse top
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.
