Hey! I literally just got done with having my buddy install mine. I did very little of the work, but overall- it wasn't very hard.
Drilling that hole was the most nerve wracking thing. We had to measure off of a window to make sure we weren't drilling in the wrong spot (like, our first line up was towards the front cap and we had to move back!).
No warranty will be voided - but if you have water intrusion at this spot, then they'll certainly not warrant it.
