Hey all. I'll keep it simple. New to mobile, want to install an NMO mount for 2M/440 in the Blazer. My question is, where would you install it? I've got a sunroof in the way up front, and then there are 5 ridges that run lengthwise in the back, so there's really no way to center it on the roof. Should I just off-set it one direction or another and call it good, or should I consider some other option? Thanks.
