Good afternoon Jon.

For that, I'd go with the PowerMax Wireless 50A RV Power Center and Distribution Panel - 60A DC Converter # PM77VR. This is a direct replacement for the WFCO 9800 and fits the same exact cutout so you won't have to modify anything. All the electrical stuff is also plug and play.

You don't have to use this feature, but it's nice that it does come with wireless control for certain circuits in the RV, such as awnings, slide outs, lights, etc.

How old is the current WFCO model? I'm curious how long it lasted.

It lasted about 12 years before the charging side quit, so I can’t complain too much.

@Jon Honestly, that’s a pretty solid run. Going with a new # PM77VR should reset the clock for you and give you modern charging and distribution all in one shot instead of piecing things together again.
