I decided that I'll do my Goffs in ww2 German theme. This means basicly german styled helmets for the boyz and big halftrak for the battlewagon and looted wagon Da Tiga. I have some orks left from here and there (killakan, stormboyz and one nob) and I based my force around them. List will be approx:
2 mobs of ~15 sluggaboyz
Looted wagon with 'ard top and boomgun.
Might just take ordinary truk (half trak) for the nobz to get more numbers, mobs of 15 doesn't sound very solid for my ear.
