Replacement Locks for Under-Coach Storage Compartments

I forgot to add, one reason I use a locking cam is because thumbturns can work loose on the road, while a Combi-Cam, or any type of key mechanism is quite unlikely to be opened just due to road vibration.

Were I in pompomgirl's shoes and looking for cam lock upgrades, I'd probably go with a set of Abloy cam locks keyed alike, just because they work well even in extremely poor weather conditions. At the minimum, I'd go with ones that have a dust shutter and a double-sided key.
