We purchased a RV Lock for our camper and this is the installation and review of that lock.
First off, we wanted a better lock on our camper because a LOT of campers have the same key! You can go to Amazon and purchase a new key for most campers if you know the number stamped on the key. We had such a key. We did purchase an extra key for our storage compartment. BTW, we have 2 friends with campers and their storage compartments use the same key as ours. One of them uses the same key for the door lock as ours did,
We purchased this RV Lock online from Amazon.com. The link is to all RV Locks so be sure to choose the one that fits your camper.
The installation was very easy and we have been using it for over a year now and it has been great.
