You can't use the fake MPPT to go from 24 to 12v, it has no buck converter. The ones that say 12/24 can run a 24 panel but only to a 24 battery.
You can run 24v batteries on the trailer with a 24v inverter to get 120v from the inverter to the camper via a 120v cord. Now you need some 12v for the camper. Use the 12v batteries there and a charger powered by the 120v from the trailer.
Some of us tested the 12v inverter draw on a 12v battery bank to run the 120v converter in the trailer with no batteries hooked up. About 6 DC amps. Same as a television.
Experiment was for a "remote power supply" concept to run an RV with no batteries in the RV. Like those MHs that tow a cargo trailer done up with batteries, solar panels, controller and inverter, and a Honda gen, and whatever else. :)
