Without furnace or 12V thermostat of the fridge your energy budget is manageable... IF there is any charging. Heavy clouds will reduce solar harvest by half or more. Rain is a real killer, zero charging.
Portable suitcases are expensive per watt and inconvenient, compared to permanent installs. BUT... Any solar is better than no solar. Even heavy energy user would benefit from a small solar. Battery likes getting to 100% once a day, and the last 10-15% are very slow, so with generator you either run it all day or bring battery to only 85-90%. Solar is good for those last 15%, run genny in the morning and leave the rest to solar.
Olympic cat heater is easier on propane than Buddy. Less fumes too.
