Interested in adding ecominical manual leveling jacks to my Semi. Done some research on a few items that are used on Semi trailers though they are overkill. The first is Landing Gears also called Jack Legs. These really carry the weight but are expensive and I would need the gear side for both sides so I can adjust each side when on uneven ground. The second manual product is called a Drop Leg will do what I want and cost much less $260 each. These are from Jost.
I don't want to invest in a fully electric / hydraulic leveling system so looking for some type of a heavy duty manual system. Each jack must be capable of lifting about 6,000 to 12,000 lb's. My 36' Semi with Slide-In camper weighs about 25,000 lb's. Goal is to level some number of inches and stabilize the rig. If I find a product that does not have a long stroke I can always just put a 6x6" post on the ground to make things work.
Any ideas? In my tagline is a link to pictures of my rig.
