I'm thinking of doing a upgrade to my enclosed trailer door right now it has the bar lock on it witch is OK but if I where in town staying in the trailer I would like to have a RV style door handle like the one I see on Bob's and many others out there. I have had this trailer since 2000 and it was used for storing work tools for all those years an had no need to change the locking setup but now that I'm retired I think the RV style door lock would be more stealthy say like in a Walmart lot or some other places where you really don't want to have the bar lock open would be a dead give away. So has anyone ever done one of these installs on a blank door and if so how hard is it to get the holes lined up. I have done many locks on regular house door but never on a RV type door lock. Any thoughts will be deeply appreciated. Thanks.
