My panel is indeed surface mounted since this is metal & perlon structure. I ran 2 ought (00) from the house to my garage with about 80ft of the 00. I could have gotten by with 3-Gauge but decided to err on the side of safety and use the largest wire the box could handle.

Since it appears that your main house panel (200amp) is also in the garage, 3-Gauge should fit the bill along with a 100amp breaker on the main box. It does not cost that much extra, since it will be a new install. Remember that if you are running the garage all from the sub-panel, you have to consider the maximum potential load/draw on that sub-panel. I would at least have a currently licensed sparky do the final hook-up. I did, just to keep myself out of trouble and up to code. Well worth it.

I used to be an electrician way back in the military, but now barely remember enough to keep myself out of trouble.
