I do dashcam install for customers a lot and figuring out where to put it so it doesn't obstruct the view is the biggest pain in the butt. Running the wire is not hard at all if you know what you're doing.
That said, personally I run FitcamX front and rear in my truck. I extended the rear cam cable (i think i got a 25ft extension or something like that) so I can mount it inside my GFC on the rear window. I like how easy it is to install and how unnoticeable it is, and how it does not interfere with my Covercraft windshield cover. With the mirror mounted ones, when using a quality windscreen cover, it takes time to get it right without hitting the mirror dashcam lol
now, i do wish I went with Wolfbox at times, since my rear view mirror is 100% useless at this time due to camper blocking it. Also the Wolfbox now has 3 channel instead of just front and rear. It now can accept a 3rd camera to be mounted in the grille area, making it extremely useful when rock crawling or going over the crest.
So, if you don't have a camper, get Fitcam X. If you have a camper like me and you go off pavement a lot, get Wolfbox 3 channel.
