@RobbieO nice system and set up. I was about to ask what it costs but saw the $349 price when I used the link you provided. Here is a screen shot of the system I bought via Amazon. I’m thinking of upgrading the indoor dash and cabin cameras to outdoor versions and using them as a forward cam to act as a dash / front hitch-trailer alignment camera and as a rear View/parking camera. i plan to mount the third camera on the boat trailer under the rear cross bar (where I usually mount the camera). The exterior cameras are not in stock so I will work with what I have until the exterior cameras are available again. I’m currently under $300 into this but the total should be close to $400 including the upgraded cameras. What I like about this system is that the display is integrated into the rear view mirror and it records all three channels simultaneously. It also ads a rear view / reverse camera to my tow rig.

this will be my third wired camera system for my third boat tow vehicle over the last decade or so and I’m hoping it will be my best and last. I like the ease of installation of wireless systems but have always experienced some kind of interference on them or the cameras overheat after a few minutes of use. I’ve never had such problems with wired systems but they weren’t premium price brand name systems either. I would expect the garmin system like the one you have to work flawlessly and hope yours does.
your storage looks as tight as mine. Do HOA rules prevent you from storing the boat at home? I have a relative in a gated community nearby who stores his boat in the backyard behind a fence. He has to drop the tower so it can’t be seen from the street or he will have to store it elsewhere, it only takes a few minutes to raise and lower the tower but he probably would have reconsidered buying that House if he knew beforehand that he would be buying a boat with a tower.
here are some old videos in which the front hitch and trailer cameras came in handy. I’ve since refined my storage policy/process so that I only have to back the boat trailer in once or twice a year, basically I park it in front of the fence during the season and behind the fence out of season and when I’m on vacation.
