I have a SuperHitch with a 24" extension and have used it with 500 lb tongue weight AND an Equal-I-zer brand hitch. The advantage is that that hitch uses solid spring bars on L brackets (no chains). The hitching process is to lower the trailer tongue on to the ball, lock the hitch, raise the tongue until you can slide the spring bars on to the "L" brackets, put the locking pins on the brackets, raise the tongue jack, hook up the safety cable, chains and electrical and drive off. No danger to feet or anything else.
