I use to own a 2013 Access Cab Tacoma.
Had the F5's with 3.5'' BS with 255/85/16 KM2's. They were a great fit and barely rubbed on the bottom of the plastic fender flare (a quick dremel fixed the issue). No issue with frame rub.
For what it's worth: Having run both the KM2 (255/85), KO (265/75), and Duratrac (285,75) I cannot express enough how well Duratracs are in the snow/ice compared to the KO or KM2. I've run BFG's for years, and was skeptical about the Duratrac, but they exceeded my expectations.
In the winter...
Nice details on the fridge mount.
It's very easy to remove the rear headrests. As a fellow AC owner, it's the first thing I did to help open up the cab a little more.
EDIT: Saw you already did it on the passenger side! My bad.
Ran OME on a 07 RC Tacoma for 100k with no problems.
Now with an '13 AC Tacoma: OME Front (LR UCA) and Dakar's in the back (with Icon 2.5 Rem Res. shocks). The set-up is great, but the rear definitely out performs the front.
In the future, I may run a fancy high performing C/O in the summer...
