What Solar charge controller should I get, for two 100W 18V solar panels. Used to charge 12v battery on travel trailer.

Curious about being able to charge an electric truck like the F-150 Lightning. The most limiting component would seem to be solar panel square footage/capacity unless one duplicates Matt Damon in "The Martian" with trailer dedicated to supplemental solar panels. Cnet guessed the batteries would be 110kwH or 150kwH for either the 230 mile or 300 mile battery. Ford can provide an 80amp at home sationary charging station and a 32amp portable "shorepower" charger when on the road. What are your thoughts? Was thinking a aux. generator may need to be considered as charging source if the RV solar system can only trickle the truck batteries.

Most of those require 120V/240V split phase to charge, so you'd need a setup that could put out that kind of power, which would be something like this: https://www.explorist.life/24v-6000w-120v-240v-split-phase-camper-solar-wiring-diagram/ but potentially even larger. At this time... a generator would definitely be necessary to recharge 'in the wild' as you'd need 18,000W of solar panels to recharge a fully depleted 110kWh battery in 6 hours of solar charging time.
