If you replace the converter, be sure to get a three stage with remote indicator. That will make your batteries last a lot longer. Converter replacement is not always easy, but it can be done. I'm pretty sure most PD units have the three stage, but depending on the supplier, they not come with a remote, or it might be an add-on extra. Just be sure you get one. I replaced my 45 with a 45 just because I didn't have time to change out any cables for the higher amps. If I had had more time before my trip, I would have upped it to a 60. And I only replaced the converter part of the box, not the fuse panel.
