Looked @ the big Vulcan cart & almost pulled the trigger (have a never expires 20% off coupon) until I noticed the Bottle placement. If you have tall bottles, prevents opening most MIGs for spool changes/setting ref's/polarity changes without moving things around. So you lose top real estate to two machines instead of 3. Adding shelves on the bottle side to stack MIG/TIG, cooler & Plasma would work if your leads are long enough or turning the MIG "backwards" on the other end works too (only a problem if your tanks are tall enough to interfere & you want 3 or more machines up there). Would be almost perfect IMO if the Bottles sat behind the cart, but then you'd need to attach more casters under the bottle shelf since getting "tippy" would be an issue & the tanks & chains might interfere with the TIG filler tube storage unless you move those as well. For what its worth, until I get my dream shop built, I'm floor space challenged so multiple carts involve moving things around to get the "right" machine & its cart out of its parking lot & It ALWAYS winds up being the one furthest from being usable.
