Tonque Jack

Any jack that will lift and lower reliably is a "good" jack. I have used an UltraFab (which many people will poo poo) for 8 years now. I broke the switch off 1 day after 5 years of use and asked UltraFab if I could purchase one from them as it was not listed as an available part on their website. 3 days later a switch arrived in my mailbox free of charge. I have heard similar stories of all the major makers of tongue jacks including replacing jacks that were many years out of warranty. Buy the one that fits your budget. A 3500# jack would the minimum size I would recommend of any of them and the bigger the better.
