Will a compressor run without freon?
Neighbors 2004 Forest River TT air conditioner is not cooling. Fan, blower runs fine, compressor also as it is hot to the touch. My experience has been if there is no freon the compressor will not run...

We can't assume the compressor is running because it's hot to the touch. If it's somehow what I'll simply called "stuck" meaning the power's applied but the armature won't turn, probably a bad compressor. And it'll heat up trying to start, power go off on thermal, try again, heat up more, etc. A non-running but hot compressor.
Another possibility: $15 or so Capacitor is bad. Compressor will not start without it. Our Coleman has four devices involved in Start/Run. One's the Fan Run Capacitor 7.5 mfd. That leaves three: Compressor Start Capacitor, Start Capacitor Cut-Out (a Relay or PTCR device) and Compressor Run Capacitor 40 mfd.
Many modern Digital Meters will test Capacitors. Since we seem to have a lot of capacitor problems with central air at home, I bought a spare capacitor to keep around for it. I've since done the same for the RV. I have a spare 40+7.5 (both values in the same "can") and a SUPCO SPP6e start device which replaces Start Cap and Relay.
Our 10-year-old Coleman needed a fan motor and I just installed a new motor. Tried to recondition the original and it didn't work. If it gets to where it needs a Compressor, I'll replace the entire machine. But in the meanwhile I don't want to replace because of an inexpensive capacitor.
