There is no gas heat wire on the 9 pin only the electric heat is labelled...do i need to use the 4 pin plug as well as the 9 pin to get the gas heat? I don't have electric heat in my trailer.

That is not a good replacement thermostat for the 7330F3852. I would recommend using part number 8330-3862. The 6535-344 is designed for a 2-ton 2-stage Underfloor heat pump.
