A little hint re starting your generator.
I have a 5KW Onan generator and sometimes I have to hit the start button several times, leaving a period of time between restarts. It is supposed to get fuel to the unit, so that there is enough fuel enough fuel to start.
Today I found that if your chassis batteries are fully charged , starting is no problem.
Just think, if your chassis Batteries , which start the generator, are on the low side, there will be little voltage left to operate the fuel pump. Hence, little fuel...no start.
I had that problem many times...Today I tested that theory. I started the RV engine to provide fresh current to the batteries, Instead of trying 3 times, the genie started on the first try. (and that was after sitting for 5 days).
If your batteries are A1, this may not mean anything. My batteries are starting to age, like many others.
Perhaps this may help someone in that situation.
