Very nice capable looking Isuzu Mark. You should post some info on your setup. I would be interested to hear what you have done.
Here are some pics of my pig. Mostly home built. Rear storage setup, cargo barrier, hayman reece towbar, front and rear towhooks, EGR delete, EGT gauge, 2in OME suspension kit, electric swaybar disconnect, belly pan, AC into onboard air, second battery, LSD, 33in Bighorns, low profile bumpstops, balljoint flip.
Front bar with winch is next then a possibly a front locker.

Belly pan
Bit of travel
Drawers and cargo barrier
Sill bars
Onboard air, second battery, catch can, EGR delete.
You can see the rear tow hooks on the towbar. I will take a pic of other front so you can see how they are mounted as its hard to describe.
The sway bar disconnect is on the rear and its a factory option I pulled from a parts truck. Very simple design. The end link is replaced with a splitable rod activated by a spring loaded pin to connect or disconnect the two halves.
