I have a fifth wheel with a ten year old PD 9100 Series power converter that works ok but I was thinking of replacing it before it goes bad and I am stuck somewhere. Any suggestions?
I'm with Barney. I would expect that PD to last indefinitely. If I was worried about it ruining a trip, I would just get a battery charger to use in advent of an emergency. That would have other uses between now and the unforeseeable.
