For generators, take a look at Northern Lights, Fisher Panda and Onan (Cummins). They all I think have units to mount in the side compartments.
Thanks! I’m familiar with Dometic, the fridge and microwave in this one are Dometic. Didn’t occur to me that they’d do mini-split heat pumps, I’ll have to check it out.
The OEM generator is an Onan. Big old thing, sort of loud, vibrates. Works very well though. I’m thinking stick with it until some major need for service crops up, then evaluate an upgrade to a newer, quieter, more efficient model.
