30 to 50 amp change
OK, this is just a thought, and I am not sure I can do it, but here goes. Our current set up in the 87 Southwind MH is 30 amp. It will only run one AC unit at a time, of course. When I had the 5500...

It's not an inherently difficult task, not much different than installing or upgrading a subpanel in a house. You'd have to replace the transfer switch (assuming you have one), the power inlet cord, and the main AC distribution panel with the appropriate upgraded versions. You also would have to think about how you distribute the branch circuits over the two legs.
Note that RV AC systems do not have the neutral and ground bonded together anywhere except at the generator. The transfer switch needs to switch both the line(s) and neutral. In this respect, the RV panel is wired like a subpanel in a house, rather than the main panel.
The 12V systems in the RV don't need to be changed at all from a theoretical standpoint, but if your AC and DC distribution are in the same power center you'll probably have to switch the DC side to a new power center (unless you move the AC wiring to a separate panel). If you have the original converter and it's part of the power center as some are, you probably will also need to replace it—which would be a good upgrade regardless, as they've improved a lot in the past few decades.
While it's not a job that's beyond the reach of a "shadetree electrician," if you have any doubts, I naturally recommend getting help or having your work checked over well by someone knowable since wiring problems can be dangerous and/or cause costly damage.
