No reason at all that you couldn't use the camper battery.. Although you would get more voltage (thus more power from the compressor) hooking directly to the TV battery with the engine running.
You will get 13.8V if you use the TV battery (engine running). The best that you could hope for using your camper battery is about 12.6V (with the compressor running). Even if the TV engine is running. The voltage drop from your TV back to your batteries is significant and would not be nearly as effective.
Try it both ways. Just pull the TV close to the tires and hook up the compressor. Then do it the other way, with the trailer plugged into the TV. I can assure you that you will hear a dramatic difference in how fast the compressor pump runs.
The other alternative would be to run jumper cables from the TV back to the compressor's power clamps. You would have to use caution that the clamps don't touch each other..........it could get quite exciting......
