Thank you Great White,,,,
I have been saying that for years.
Why change locks on a "cardboard box" ?
Most RV compartment doors are made of a light weight composite material that can be cut open in less that 5 seconds with a razor knife..
or busted open with a solid punch from the average size man.
If a person is worried about someone getting into their RV's storage compartments..
they should go to their local metal fabrication shop and have custom made doors constructed of aluminum deck plate installed.
When the metal doors are installed make sure to have the door frames upgraded also..
The metal shop can make the door frames to match the doors..
Upgrading to a metal door will do no good if the door is installed in the cheap thin aluminum frame that came from the factory.
The door frames should be at least 2" wide and made of deck plate also..
Then the frames should be installed with a 2" wide deck plate "backing strip" on the back side instead of regular washers.
Use "Bolts" not screws to attach the door frame to the RV... and either peen the bolt threads or use a locking nut and/or lock washers.
Once you have a decent door you will have a door thats worth installing a decent lock in..
