This is a tough question.
A kw is 1000 watts, so if you have a 1500W space heater, it consumes 1.5kw. If you run that space heater for 1 hour, you will consume 1.5kwh, and so the cost (at 12 cents/kwh) will be 18 cents.
Since the space heater will likely cycle on/off while keeping your coach toasty, it's hard to say how much energy it will use per day because it's not on all the time.
Other appliances similar. Your fridge and A/C unit(s) will cycle on/off during the day depending on ambient temperature, how often you open the door, etc.
So, even if you know the wattages of every appliance, its tough to estimate with any accuracy how much you will consume per day.
That's why you need to buy a Kill-a-Watt or similar device, and record the energy usage of your WHOLE camper over a period of time. Only then can you come to a reasonably accurate estimate of your power consumption.
