The has plenty of storage room underneath. I made loops for the bottles and put little bolts with wing nuts to keep them from rattling around (I hate that). The little bottle is argon and the bigger bottle is tri-mix. I have bulk bottles to refill from or use while in the shed, but pushing the little 211 around is a nice way to work.
I know the idea isn't original, but I thought it would give a few laughs.
