I don't like fuses, so I went with Blue Sea marine breaker panels.
It's easy to see when a breaker has tripped (each one has a pilot light), I don't have to worry about spare fuses, and a flip of the fingers turns off a circuit for troubleshooting or upgrade work.
Also, all connections to these panels are made with ring terminals (secured with lockwashers), rather than the setscrew terminals found in most RV electrical gear. Ring terminals are much less likely to loosen up during travel. A loose setscrew terminal can cause a literal meltdown or even a fire--I've seen it happen.
As you can see, I also replaced all the AC breakers, and replaced the converter's failure-prone automatic transfer switch (ATS) with a dual-breaker lockout pair. Yes, it's manual... but it's much less likely to fail than an ATS relay. Again, I've seen those go bad more than once.
These are not the cheapest ways to do things, but they are arguably the most reliable.
