This X2
If you do it right, it's not really permanent, it could be un-done. Have you ever seen what some of the body shops have to do to fix some of the wrecked vehicles?
Just sayin, don't be so scared to cut it up... Later on if you decided you wanted it back to original, it could be done.
If they can replace the entire roof after a roll over, and know one notice, then surely they could fix a cut-out in the back of the cab...
Just some food for thought
Never thought about it that way. But I'm more worried about myself cutting that big of a damn hole.
