I tell you the problem with these contraptions....
the typical garage is maybe ~20' long if that, and maybe 20' wide if you have a double door....2 car....IF you are lucky....
and a 8' ceiling....
SO lets assume you want to do an engine/steering up front, remove front wheels, maybe a trans out the side....need get the rear up too,
typical house is an 8' ceiling.....
MY solution has been jack stands and a GOOD floor jack, get that SOB UP there.....enough to slide a auto trans out the side of the car, with a set of wheels/dolly under it....
OH, another trick, a guy gave me a old slick rubber mat from a bowling ally about 1/4 inch thick and slick on the top side....impervious to oils and water....about 3' wide and 4' long....
needless to say, it's FAR better than any creeper.....
AND adds maybe 4 inches of very useful clearance.....
