I bought a set of 4 heavy duty Libre 24" 7500lb leveling jacks. They are made using 11 gauge steel. Cost was $135 on ebay in 2020. I started fitting them to a LeSharo. A LeSharo is similar weight as a 21ft Toyota MH. I started with the front. Got one fitted. Then realized they really are just stabilizers. If you think they are a jack that will pick up the RV - you will be disappointed. 2 would not pick up one end of a 6,000lb RV. These "stabilizers" have so much friction in the threaded screw under load that the lift is limited. The thread is rolled. Not machined/cut. There is simply a steel thrust bushing for the screw - not a ball bearing or plastic thrust bearing. I stopped installing mine and am watching ebay and other sites to buy matching pickup truck jacks similar to one I have. They actually will lift the RV.
