Upgrade exterior hatch barrel lock and latch

[RedJeep]

Hello friends. I have an 08 Georgetown class A. It has been great but there are some cheepo components I'd like to upgrade. In particular, the cheap barrel latches on the outside hatches. Has anyone come across some product or method to upgrade to a more modern style latch? Maybe a paddle latch or something other than the barrel latches and locks that came with it?

I have replaced all of mine with These ,they can all be keyed alike so I only have one key for everything. Just pick the size and how many you want.

I also like that they have a cover on the key slot that moves when you insert the key,thus keeping all grime out.
