What are you using for a wax? Just run of the mill Turtle wax?I have a small Columus Variant and simply torqued the fasteners snug in combination with blue thread locker. I did not tighten to a specific torque. The tent has been mounted for 18 months and has not moved or come loose. Yes the 6 NW should be 6 NM. I have a torque wrench and could have hit this mark for the fasteners but it it seemed unnecessary. The most likely consequence of excess torque would be to bend the plate that mounts under your cross bars. Higher torque will not stress the fiberglass of the tent given how the recessed metal track in the base of the tent takes all the load.
It is a great tent. So easy to deploy and stow and much lighter than most of the competition. But be sure to wax it at least every six months especially if stored outside. The gelcoat finish otherwise oxidizes very easily. This is my only criticism of the tent.
