Coupler Lock for Underslung Trailer Coupler I am looking for a highly secure hitch c

Question

Question:

Hello, I am looking for a highly secure hitch coupler lock. The AMP56FR looks like a good candidate. 1 Will the AMP56FR work on my RV? SEE PHOTOS OF MY HITCH COUPLER 2 Do you recommend any other make/model coupler lock? Which is best in your opinion for my RV? COMMENT: I am pretty sure that the Proven Industries 2516-J will work too, but it is really pricey. I like the lower cost of the AMP56FR. 3 How hard is it to defeat the AMP56FR? I know this is somewhat subjective. My RV: 2022 Jayco Feather 24BH see photos. Width of MY flange is a little less than 4-3/4 inches. Height of coupler looks like my tape-measure it fits in the 2-7/16 inch width window.

Thanks for the picture of your trailer's coupler, from that I can tell you have an underslung coupler which his what the AMP Lock Coupler lock part # AMP56FR is designed to fit. It also works with the flange width you mentioned as well.

This is a harder to defeat coupler lock that would work well for you. I would recommend it highly because of that.
