I have the built in Onan 2.5 Kw. in my '03 camper. Zero problems with it. It starts every time.
I like the convenience of the generator for what we use it for. We run it briefly for the microwave or toaster to fix a meal or to run the AC during a lunch stop. Really, I'd probably be just as well served with a big inverter and solar system but the camper came with a generator.
If I was going to use the generator a lot for long periods of time I would rather have a portable gasoline model. This would get it farther away from the camper and the fuel would last longer.
So, it all depends. How are you going to use your camper?
