My air cools good but will not cycle on and off runs all the time. Any help would be welcome . Thanks

Since this is in travel trailer section you probably have a wall thermostat. See if it has an AUTO fan setting. If it does the fan will cycle on and off. If you set the fan on high or low the compressor will cycle but the fan will run continuously.
My bet is the thermostat is set on high.
