The only way I would go propane is if I didn't think I'd need a genny often. For occasional use the propane would work - though it would be a big factor when valuing the coach?
My LP powered 6.3 kw Onan runs quietly at 1800 rpm.
BTW, I would have preferred a diesel, but for me, LP was not a deal breaker.
IMO, it's imposable to find everything you prefer in one coach, some compromises must be made, (or you will never buy).
