I can't imagine 2 adults sleeping on a converted to bed dinette. Maybe that's a larger dinette than usual - but they are usually small beds.
I might like the central vac, but wouldn't pay extra for one (that's something that if it came on a used unit, would be nice
, to me). I disagreed about the convection v the regular oven. Prefer my convection oven. Even with the amount of boondocking I do - I don't use the regular oven. If it needs an oven, it has to wait till I have hookups so I can use the convection one. So, this is totally going to be which YOU prefer. All these things are so dang subjective.
I would want solar power, with enough batteries - to almost never (or never) need a generator. That is the way I went with this rig, finally, and would never want to go back. As green as I can make it. If the rig has a generator, I'd want Onan over Generac. (for service reasons) and would want it to be run on gas, not diesel. If it doesn't have a generator or solar, you have to get one or the other - Honda makes great generators, also.
