generator output

New guy here still in the research phase before purchasing. Question on generators, looking for info on output, is it better to have a smaller generator running a full output or a larger one at 50%? What I am curious about is I will be using the unit at the races and need to power a refrigerator, and a/c units and microwave. I am trying to decide between older Prevost coaches with 17.5 and 20 kw gensets or newer motorhomes with 7.5 to 12.5kw units also see the higher end coaches seem to have dual inverters instead of one is this redundancy like in aircraft or does it serve a useful purpose? Thanks in advance for any and all responses, Scott.

WIth 7.5-12.5KW, I think you'd be perfectly fine. They size them for what the coach needs.
Dual inverters are so you can double your AC wattage output. Just like having multiple batteries as opposed to one giant one.

Some coaches will have two inverters. One large one smaller. The smaller usually runs the TV and entrainment equipment. This way it's not needed to run the larger and less efficient inverter all the time.
