Does anyone know if it theoretically is possible to charge the Lightning through the outlets in the bed (thinking of solar panels on top of a camper). I am aware it would be only a trickle charge, but I’m curious if there are any restrictions/safeguards against doing this.

You want to back feed through the 120? I don't think that's possible, those outlets are all gfci protected which i think would poetically trip if you backfed them. I think you'd have to charge an intermediate battery and use a 12V/120V inverter and a Level 1 charger plugged into the J1772 I think. Definitely doable that way, can't remember where the goal zero yetis top out for solar but that might be an option.

Not through the 120V bed receptacles without re-wiring and modifying their function. You could probably rig something like a solar powered EVSE using the truck's charging port. As you realize, it would yield a minimal amount of power delivered to the traction battery. A full-sized four-panel array might net the equivalent of a few hours a day of Level 1 charging.

Like @KEIlhorn said, get an inverter and plug it into the mobile charging to plug into the normal charging port of the Lightning, here an example for a 12VDC to AC inverter for $50 on Amazon - https://a.co/d/eWJ17K6

You probably won’t be able to get much more than 600 watts from the solar panels on a small area such as your bed or camper but you can what’s get a better inverter if it produces more. Also, keep in mind what DC voltage output the panels are producing to get the correct inverter to convert your specific solar panel output to AC power to plug in your mobile charger properly.

No. You cannot "back-feed" through an inverter in this way.
