I was thinking of making a goblin, or more traditional a gnome, which is going to ride, leaned back in a light brown leather seat, mounted on a large sized warforge.. A litle guy who is “drunk on being a big badass”.

My character obvious needs ranks in craft/profession to make modifications, (and “heal” checks), on his great big mount of menace.

But how to be the best master of such an heavy intimidating (magi)mechanical monster?..

Class/feats etc..?
