My 2008 model Starcraft 14rt originally came with the ELIXIR 30AMP model single mode converter with only one 120VAC circuit breaker and four 12VDC fuse positions.
I changed mine out with the WF 8900 series power distribution panel and a WF8945 converter/charger unit which was suppose to be a three mode smart charger but I could never get it to go into smart mode charging. I later on added a PD9260C converter/charger unit only in a different location closer to the battery bank. I left the WF8945 converter unit in place and just flip the circuit breaker to turn on either the WF8945 or the PD9260C unit. Have a back-up now...

The WF8900 series power distribution chassis fit just fine where the older ELIXIR chassis was located with just a few mods needed to make the mounting hole a little larger. It took around three hours to re-wire all of the AC and DC power cables in place as they were already relocated to this same area. I did have to rewire a couple of the 12VDC cables as they were too short. The new power distribution panel gave me more 120VAC and 12VDC circuits with their separate circuit breakers and fuses which was a big plus. I also got rid a hugh rats nest of wiring behind my original ELIXIR install.
