Since the module says ATS50 I assume this is a 50 amp rv.
Post the brand and model number of the breaker/fuse panel would be helpful.
Otherwise Randy can probably set you up with what you need:

Randy is the BEST! Bought a couple of converters, inverter, ATS, etc. from him over the years, his tech. support is awesome, he knows his stuff.
if the heavy gauge wires from the generator and shore power terminate at the lugs then I doubt there's an ATS, but I could be wrong. If you trailer is 50 amps then there are two hot feeds, one neutral and one ground. Each hot feeds one leg in your distribution panel (they're called a "Bus" and 1/2 of the breakers are connected to each Bus, may not be evenly distributed but you get the picture. Get a volt meter and check that you have 120 volts between each hot leg and neutral. You might be getting only one leg of power.
On shore power each leg is connected to a hot at the pedestal. On generator there's only one hot, therefore when running the generator, in order to get both bus hot there's a jumper between them, that jumper then drops out of the circuit on shore power; with an external ATS the jumper is on the output side of the ATS generator contactor.
