So I've been looking through countless trailer jacks and not finding what I think I need. Wondering if I'm looking for something that doesn't exist. I have a welded on snap ring jack on my popup camper. I did the "axle flip" and now it doesn't offer me the range I want. Sounds like a simple fix, right? I think what I want is a snap ring mount (so I can just pop off the old and pop on the new), with 15" travel, folds up for travel, and has a wheel (or two). 1200# capacity is ideal. I'd be okay with 1000#. Side or top wind is fine. Seems like it would be easy to find, but I can't seem to track one down. Lots of 15" travel without a wheel. Some that are bolt on. Some that are 10" travel. Is there a reason a 15" lift jack that is snap ring with a wheel doesn't exist? Thanks!
