Yeah, if you were designing an RV without A/C, it would be better and cheaper to apply the cost of a generator towards a larger inverter with higher capacity converter, more batteries, plus maybe some solar. Air conditioners are still what makes generators necessary for anyone who boondocks.
Also to Jamie’s point, compared to my previous Onan, a portable generator has to be protected from rain, and depending where you stay, from theft. A built-in doesn’t have these issues.
