Darius,
Are you talking about the AC (shore power) panel or the DC panel.
My coach is OLD, and the essential components are still shelf stock at any big box. The DC panel, if it includes the converter may be a good idea. The modern converters are Soo Much better than most of 20 years ago, this might be worth doing.
For the last bunch of years (after I came ashore from merchant ships) I have been in the business of upgrading the electrics of performance cruisers (these are retired racing sloops). Depending on what your current panel is, it might just be a waste of time. But, if you need more circuits (not uncommon) you might, add an additional panel or replacement panel may be a good idea.
In either case, I am available to listen to you plan and provide what help I can based on my experience. I'm here a lot.
Do you know what the difference is between a boat and an RV???
Water will leak out of an RV.
