Hell yeah. Gorkanaut's so fun to play with. The most orky way of playing is to run Dread Mob, use Superfuelled boiler for assault, force sustained hits x Dakka Dakka Dakka strat for maximum hazardous rolls, then Bigga Shells for Bigga Gitz if you're shooting vehicles. Do 12 mortal wounds to yourself, charge their backline, then explode in a fireball of glory.
Edit: Also, remember that a Mek's Mekaniac ability states 'until the start of your next Movement phase, each time that VEHICLE model makes an attack, add 1 to the Hit roll.' - works for the whole of your and the enemies' turn, and works on both shooting and melee.
