Back to basics:  The start button is also the primer. Be sure to press it to off until the light goes out then press start.

You also might try starting it from on board switch instead of remotely.  Begin by flipping off its circuit breakers to remove all loads.  While next to the gen you should hear its fuel pump "clicking" while priming.

Low oil level will prevent the gen from running once you release the start button.

If we can't talk you out of a portable and all the PIA it will bring.....  A couple of weeks on the road will convince you.

Thank you for all the added info and advice !!!?

I am going to go with the advice given here and get the Onan going then I will see what other power options suits my needs.It's obviously best to have that in running condition and then a use stand alone unit as my backup.

I am having the fridge looked at  today..Will be using a local rv company to service the generator . Over the weekend I was able to get it running for a very short period of time and now getting the switch light blinking 3 times for service.

Found leak coming from the Dometic Sealand toilet handle. Would that leak effect the pressure to the shower head and or sink faucets?Any links,tips etc on getting that model fixed would be much appreciated.

If the toilet water valve is leaking, replace it with a new one. Could be that sometime is it's life someone forgot to winterize it and it froze. Water leaks in an RV can do more damage then just about anything else.

Hope you get the genny fixed. My brother has a 4 KW Onan in his class BT Cruiser. Had to replace the carburetor with a new one to get it running again. Left the un-lead gas in the carb to long.

Good decisions. I would wait and see if you need an additional generator. If you are boondocking you might want to consider adding solar and additional batteries. Wait for any major purchases until you find your RVing style in about 6-12 months.

Regarding the toilet if you want to fix it this is a DIT project, just check you tube. We ended up buying  a new one after I broke an additional piece of the toilet. They are not expensive. Pretty easy to change out.

Is the main breaker in ur class c 30A or 50A?  Convection ovens will have a lot of amp draw. 

I doubt there are many Class C's with 50-amp service, at least I've never seen one.  We have a Class C with no oven, too, and we have a microwave/convection oven.  It works just fine on our 30-amp service whether we're plugged into power at an RV park or running the generator when boondocking.

I don't think anything in an RV takes more than 15 amps, individually.
