With the Sherpas, the mounting bolts only use a couple foot pounds - the spec was in inch pounds (I may have misread it as foot pounds the first time), and all it needed to do was lightly compress the bonded washer, not compressing the rubber block. The first time I installed it I overtightened the bolts, completely squashed the bonded washers, and needed some replacement hardware to re-do things correctly. Too much torque can also damage the nuts captured inside the roof.
