Though described as boltless, the side steps, particularly for the Tribeca, needs drilling. There apparently are no mounts under the car.
A step in the directions require you to manipulate a U bolt through one hole, and then out the other.
Romik had another supplier, but their link didnt work. They're based in Allentown, and if I can pick one up today, I might go there and pick it up.
The most frustrating thing about them (trucknsuv) is their communication. Calls and emails are sent somewhere, and it takes them some time to respond. It really doesnt give me much confidence in ordering from them.
