Howdy and welcome to Just Answer.  My name is***** and I am a Master Certified RV Tech. I understand how frustrating RV issues can be.  I have been  working on RVs for 35 plus years.   i see you are trying to replace your old generator.  You will need at least a 5500 watt generator to handle 2 A/C with 2 breakers on the genset.

Onan has a great 5500 watt genset

Ok,When it does start it want stay crunk
RV Mechanic: KevinS121,
 replied 1 year ago

there might be a fuse on the panel above the start switch, low oil could cause that, no electrical output could cause it as well.  What is the model number of your genset?

Low oil pressure switch could be faulty.

I wouldn’t know where to start I’m just gonna replace with a new one. That way I can ensure it’s gonna work. I should be able to wire into the new generator right?
RV Mechanic: KevinS121,
 replied 1 year ago

yes.  you will have the same type of wiring.  You might have a different place for the wires and fuel to hook up and the muffler is built into the case.  All you will have on the bottom is the tail pipe.  The new one will a whole lot quieter

It has enough watts, but some of these generators will not pull 2 A/Cs very well.  I have not dealt with this particular brand.
