I just recently bought a 2015 Thor 37MD toy hauler. Still getting familiar with everything. Question: in the rear bedroom (with fold out sofa bed) there are 4 ceiling vents with no air flowing from them. I'm assuming these are A/C vents..right? If so how do I make them work...thought there may be a control somewhere that I haven't found yet. This room is to warm to sleep in or even sit in. Texas heat is brutal! I will appreciate any guidance on this issue. Thanks

Sounds like your thermostat isn't on. Look for the thermostat which will look similar to your home central air/heating thermostat on the wall, probably in the bedroom. Turn it to cool and then set the temperature below the inside temperature. It should come on and start to cool. This is with shore power plugged in, right?
so the way they work, is you need to shut the fast cool vents on the over head AC unit. This will force air into the overhead manifold. If you have no air flowing thru the vents, there is something clogging the vent ducts over head.
Is there air coming out of any other A/C vents when the A/C is running? As a used MH you have to consider that a previous owner may have replaced the A/C with a non-ducted model.
