Anybody LOVE their Onan Microlite 2800 ?

No experience with that Onan version, our experience with their 4000 and 5500 models has been very good. A bit of annual maintenance and Seafoam when adding fuel has kept our units running well. There are portable inverter gennies that that might be an option in that price range on sale at Samsclub or Costco occasionally, if Onan 2800 is indeed running well under significant load and it meets your requirements, you could get it knowing there will be costs pertaining to upkeep and possible future repair. Both types (portable & onboard) are not difficult to maintain and repair, the Onan is imbedded into the RV that makes it challenging.

The Onan 2800 is the unit I had in my Keystone Challenger. It never failed me in all the time we used it. It handled my load without a problem, the maintenance was minimal. Loved that unit.

If it runs and produces the proper electricity it likely is a good find. Most common problem was carburetor fouling.
