Trailer and RV Latches and Locks That Hold Up on the Road
Trailer and RV hardware lives a rough life: vibration, weather, and the occasional hard bump down a gravel road. That is why the latches and locks here are judged less on looks and more on whether they stay put and keep working. Corrosion resistance and a positive latch that will not rattle open are the whole point.
Sizing and mounting pattern are the usual gotchas. A replacement latch has to match the existing cutout and the panel thickness, so measure the old one and the door before ordering rather than after.
Master Lock Coupler Latch Lock Solid Brass With 3/4In (19mm) Shackle
This is Master Lock's take on a trailer or RV latch or lock, in a brass finish.
Check the mounting and dimensions against what you have before ordering.
Master Lock Trailer Coupler Latch Lock Adjustable Stainless Steel, Keyed Different, 6 Ing Positions From 9/16" (14mm) To 2-3/4" (70mm)
This is Master Lock's take on a trailer or RV latch or lock, wearing a stainless finish. It comes keyed different, so it carries its own key.
The listed size is 9/16". Keyed different means this carries its own key, which is secure but adds another key to the ring if you buy several.

Choosing well
Match the part to your door thickness and cutout, favor finishes that handle weather, and keep a spare if it is a part you would hate to be without on the road. Small hardware, but it is the difference between a secure bay and a flapping door at 60 miles an hour.
