We have a diesel 8K variable speed on-board generator and it is reasonably efficient and super quiet inside and actually pretty quiet outside. It is well integrated into the MH with AGS so it is starts when batteries are low, when AC calls for it, and it can even be set to sleep time hours and daily charging. It is always our first option.
I wouldn't sell the Hondas if I already owned them, but I wouldn't go out any buy any either. My buddy was in the same predicament as you, and he ended up selling them because he never used them and continuously had to spend time with them every spring cleaning out gummy fuel.
