Yes, how overall effective it will be I guess depends on size of Jackery unit. Much easier for us to utilize onboard solar and/or genny when off the grid in our motorhome, one button convenience to enjoy all the creature comforts our rig provides. Unless we are RVing in extreme temps solar covers most of our power demands, sporadic genny usage covers extended convection microwave usage and quick recharging of battery bank with our 100 amp smart charger on cloudy days or when parked in shade.
