Why bother with the warranty on this?
I got a recall letter too. I checked my serial number and I'm on the replacement list. They want me to bring the camper in for inspection. Not that they have a replacement in stock. They just want to verify that the regulator is on the list before ordering a replacement. I just covered the camper for winter storage and have better things to do than dropping my camper off for service, dealing with a ride home and back, and leaving it for an unknown period of time for service; all for replacing the thing with another cheap regulator.
So my point here is that if I'm replacing the thing, I might as well get a better regulator. The tank cover has an access door on the top that should make getting access to the tanks easy. You can't see the tiny indicator on the regulator that tells if the tanks have switched unless you pull the cover off. That's an unnecessary PIA. I ordered a replacement regulator, Cavagna, that has the indicator visible from the top. Yea, I could probably have gotten a fee replacement but the cost of my time, gas, and aggravation isn't worth the trip.
