I'm not a pro - but built one for my 356G project. It's a bolt together deal and when you pull the 2 upper or lower leg bolts - it folds flat for storage on the wall or against the wall. You can take it totally apart if you want to.
It has leveling casters on the 4 corners - with just levelers in the center posns. The casters are non-marr types so they don't tear up my epoxy floor but they are expensive - so I have an option for replacing them with a less expensive type and adding levelers in the lower hoop. If anyone is intersted I can post the measured drawings and materials listing.
PS, Make sure you set the lower rail above the height of your engine hoist so you can roll the hoist in/out.
