Sometimes I wonder about taking a FIC or TriMark door handle, putting all the measurements into a CAD program using calipers, then hitting a place that does metal sintering so they can make a door handle exactly like their offerings... but made out of Iconel 690. That way, it will take a lot more than just pot metal fatigue to break the handle.
This is one of my peeves with the RV industry. A RV should at least be either up to the grade of a car lock or a lock on a house front door, because a rig does both functions. It needs to have at least a key as secure as the average "laser-cut" keys on most car locks (well, "laser-cut" keys are not really modern... coin lockers had that type of mechanism called Bell locks since the 1970s.)
