Installing a Deadbolt on entry door

Look at Trimark latches. They make most of the door latches used on all brands of RVs. The one on our Gulfstream is very touch, and the deadbolt is very solid and the latch it goes into is also very solit and sturdy. However the brand does have a reputation of the bolt breaking, and a number of horror tales about getting locked in or out. Since getting locked in and replacing the OEM lock on ours, I do think that the newer models have minimized that problem. After what we went through tring to get our door open and get us out of the RV, I can testify as to the toughness of the latch and deadbolt assembly. There are a couple of easy ways to do it, although there are only a few that know how, and none of tem are around when you really need them.
