Since you already have it, sure. A 40 year old power center is overdue for replacement. They do not get better with age, and the old ones tended to be battery
If I was shopping for a replacement, I would buy a PD 4135 instead. Its a very good unit, made in USA, and costs about $100 less.
The original power center on my 1977 Trillium
had ONE AC breaker and just ONE DC fuse, 72watt total (6A). Not even enough DC to operate the original interior lights!
The PD unit I installed has 30A AC, with 5 circuits, along with 6 DC circuits. I'd consider it overkill for my Trillium
. And I have converted the interior lighting
to LED, which reduces that load by about 90%.
Of course, I had to change out my main power cord to a 30A cord. While doing that, I went with a surface mount plug in on the side of the trailer, eliminating one mouse entry point.
