Going to be installing a 6" stack thru the box. What did you guys use to cut the hole thru the floor of the bed?

 

I have not done it on my truck, but on others I used a rotozip. Make sure to drill a small pilot hole and measure around where you are going to cut... have someone else look too. You never know what you're going to miss, and cutting a hole in a bed is hard to undo...

 

Thats the only tool I didnt think of... I was really hoping to use the air powered nibbler but with the line-x it was going to be too thick. Didnt think that the air saw would do a good cut, and i wasnt able to find a 7 inch hole saw... Roto-zip it is.

 

Has anyone tried putting a stack thru a tonneau cover?

 

I've seen it tried, but not successfully. You'd have to cut a long oval hole to have correct use of a hard tonneau, and the vibration and heat will wreck the cover and mounting bolts. Never seen it on a soft one.
