Adding 12v Connection for Starlink Mini: which side of trailer? (need opinions)

I'm going to add a 12v connection for my starlink mini. I am waffling on which side of the trailer to add it on. Let me know if you see me doing anything stupid…

Passenger side: I can wire directly to battery/bus with inline fuse, run line to rocker switch mounted near battery cutoff (or anywhere along bottom of dinette seat base), then drill hole in side of trailer for bulkhead port. Sounds easy, shorter wire runs, port located next to outdoor power outlet.

Driver's side: Wire into fuse box, mount rocker switch some where along base of dinette (would love to mount it up near stereo, actually) and have bulkhead connection located in the Nautilus (P3) compartment (where coax, etc. already are). I am thinking I'd use the hole for the black tank flush since I don't have a black tank and there's just a dummy plug there now.

If I decide to tie into fuse panel it'd much easier to use a piggy-back fuse, but that seems a little too DIY to me, any thoughts on this? If I splice in from the back does anybody have any pics of what they've done in the past? (I am more of a visual learner.) I don't think the fuse panel has any spare slots does it.

So here's what I am looking at getting (any input on this is welcome too):

Rocker Switch

Bulkhead Port

12v Adapter/Step up
