Question:

I am looking to replace the trailer jack on an old camper. The hitch is A-frame style. I see you have a lot of 3-bolt A-frame jacks, but I need a 4-bolt. Do you have anything like that? I am hoping not to have to modify to a 3-bolt, and am not particularly interested in a side-mount.

Almost all A-frame jacks now have the triangle or round mounting plate with the 3 bolt-3 inch on center holes. We do not carry anything that has the 4 holes. We do have some electric jacks like the Stromberg Carlson Electric Trailer Jack - Drop Leg - A-Frame - 23" Lift - 5,000 lbs - Black, # JET-5000 that have a round plate to mount, but the holes are still lined up with the triangular mount design.

Unfortunately you will either have to weld the bracket or drill holes in your coupler for modern standard trailer jacks. My recommendation is to drill new holes and use a jack compatible with your tongue weight capacity because that's how the jacks are designed to install and welding may void its warranty. I've attached an article on trailer jacks to help.

Another option would be to change out your coupler with a new one that has the standard bolt pattern like Demco A-Frame Trailer Coupler w/ Jack Hole - eZ-Latch - Black - 2" Ball - Bolt On - 10K, # DM14793-81.
