Before following this thread, I didn't realize propane tanks were so much trouble. My DP is 21 years old and my tank is pristine. However, it is mounted inside a basement compartment, which is why it never needed maintenance.
It's a shame that RV manufacturers mount such a device open to the elements where it will rust away. Amazing.
Does anyone with an exposed tank do regular maintenance on their tank? I am ignorant of such a process, but it seems like a periodic brushing, maybe sanding, and then touch up paint would go a long way to preserving the exposed tank.
As an aside, we heat our home with propane and have a 1000 gal tank outside in the elements. It is 40 years old and still looks good, but I brush it, and sand it and paint it from time to time.
What am I missing?
