I have a 2014 Leisure Unity and the exterior lock failed recently? It is the regular latch not the deadbolt which doesn't fully retract and keeps the door from opening. It has a Trimark #060-1650 lock on it which is available at Camping World for about a hundred bucks. A little Internet searching reveals many complaints about the Trimark locks, and I'm thinking that they did a re-design with this model being the latest version. From what I can tell I think I may have the latest version, but this rig is only 3 years old and I only use it a couple of months a year..so why would it fail already? I did open up the lock and found a small, white plastic piece which seemed to be the problem as it sometimes keeps the throw bolt from working properly. Does anyone have any experiences with this problem, or with the Trimark replacement locks from Camping World, and from their so called re-design? Is this new re-design any better do you think...or still a lot of problems? Thanks for any guidance you can provide! Also, is anyone aware of any other brand of replacement lock that would fit without any modifications? I've emailed LTV recently about the problem and am waiting to hear back from them. Any comments on your own experiences would be appreciated.
