adding more vents is relatively easy. most ductwork is a rectangular plenum running most of the length of the trailer from the front and back AC vents.
so, if you remove a vent, you can likely see what the run looks like, and if you have two vents in a row, that shows where the duct is, and at the last vent run a fish tape to see how much further it goes. likely the length of the trailer.
then just either cut a hole for a vent or if you want to be real neat, get a large hole saw of the diameter needed.
Makes perfect sense. Thanks for the tip
