I'm not familiar at all with generators. I'm looking to buy a generator/inverter for my pup (Rockwood Premier 2514G). It must be quiet (something like a Honda ultra quiet). I'd like to be able to use my pup outlets when boondocking in the Fall. Specifically the heated mattresses. Pup has a 30 amp plug and I have a 20 amp adapter for it. Id like it to be able to run for at least 8-10 hours at night. Perhaps it could also be used to run a CPAP machine? Any suggestions for a quiet generator? Thanks Also, is plugging the pup into a generator going to recharge my batteries (like being plugged into shore power)?
