I would hold off buying a new door lock until you have the RV at home and can compare what's installed to what you can buy. There are a couple of "new style doors" that have lock cutouts that won't accept the "conventional RV door locksets" and on at least one of those "new doors" there are NO compatible locksets.

So, it's quite possible that the lockset you order won't even come close to fitting the door on your trailer....

That said, RV doors are not "built with security as a primary concern"... They are "extremely lightweight", are not much more than a 1" sheet of styrofoam with an aluminum frame around the perimeter and a couple of 1/8" fiberglass or 0.32" aluminum skins glued to the inside and outside of the foam sheet.

You can "literally" punch a hole through the door with a screwdriver and anyone weighing over 150 pounds can easily kick in the door... What I'm getting to is that even if you can find a "high security lockset" for your door that will fit the hole, it won't make the door any more secure than it already is....
