I'm not sure that you haven't done everything you can do, Denny, aside from drilling out the lock to get some sort of access to the actuator mechanism. If you do use a locksmith, be exceedingly careful about your choice, since there are a lot of syndicate-run (Russian) rings out there, with big ads in the yellow pages; look for older military veteran types in the small buildings, or ask an experienced friend's recommendation. Since no one answered your previous post on this subject, I reckon I'd give the guys at Beaver Coach Sales, Bend Service Center, a call and see if they have any other ideas: 1-800-843-2967. They've likely been there, done that many times.
You might also check other Forums with a large member base and experience, such as FMCA,

Normally, though, you'll want to come here first for more "species specific" and other input. I used to frequent RV.Net a lot, but got discouraged with their advertising and site quircks, and found the BAC Forum much more user friendly and comfortable.
