Been there, done that. An artic was the very first thing I tried.
I can't find the pics anymore but it was pretty fragile. It used 2x2
turntables for the pivots.
I did a 5 unit double stack just before I left CO. See:

That uses technic 2x2 tile with center technic pin for the pivots. Much

Zonker Harris did a Thrall-ish double stack too, also using 2x2
