Why “no way”
My Yakima rack "landing pads" are bolted right through my truck roof to the space between the inner roof and outer roof.
They can still steal the towers, but not the pads.
the towers are fairly cheap.
It is probably the securest way to install racks, and are better than the factory rails on other vehicles.
The first hole you drill hurts the worst. Once that is done, the rest are painless!
