I have been waiting to buck the new water fill door on until I installed the lock. There is always some waiting involved. This time it was waiting for a stainless steel cam lock to ship out from California. No, not Corona, California, Northern California. Eureka, I think that is Humbolt County. I wanted to make sure everything fit just right incase some kind of adjustment was needed. It all worked perfectly, and I was able to use my bucking bar and my Brown Tool rivet gun. The real kind of rivet gun, the kind that sets solid rivets. I am very happy with how this door came out. It actually closes tighter and now can be closed and locked so it does not flap in the wind. No more aluminum tape while on the road.
