RE: Battery Charging on Truck Camper
Certainly if you have a higher voltage and high output module, you have to use a MPPT controller. The sky is limit if you want complexity. I thought the OP just wanted to keep his battery topped up. Actually with a smaller wattage panel, the MPPT consumes a significant amount of the output. As you correctly stated PWM is simpler and harvest the maximum amount of energy available. During the peak of summer the battery is likely to be full by 11:00 am if understand his use case correctly.

RE: Battery Charging on Truck Camper
Solar is not complicated. Get a 12 volt solar panel (80 watts will suffice), get a cheap PWT charge controller (10 amps will work) and fuses if you wish. Mount the charge controller close to the battery (connect with 12 awg wire is fine). Mount the solar panel on the roof using Z brackets, then run the same 12 gauge wire and connect to the charge controller. That's it.
