Moisture help

I have a 24 ft travel trailer and I’m currently in Arkansas. Moisture build up on the windows each night is pretty bad.

I bought a dehumidifier rated for 900 sf and my trailer is about 225-250 sf. One of the pics shows how much moisture it collected over 2 days and nights, maybe 1/2 a cup.

I also have 2 containers of DampRid but I’m still getting moisture build up on windows.

If I cook in the trailer, I run the vent fan over the stove to try to remove any moisture from that. One night was using furnace, one night was using electric fireplace for heat.

Not sure what else I can do.
