ANSWER: Hi Bobby, Yes, with a couple of adapters you can plug your 50 Amp Motorhome into a 15 Amp household plug. First, you will need a 50 Amp Female to 30 Amp Male adapter. Either one of the 2 adapters listed below will work for you.
Camco 55185 RV 18" PowerGrip Dogbone Electrical Adapter with Handle
Dogbone Adapter with Handle, 30 Amp Male to 50 Amp Female
You will also need a 30 Amp Female to 15 Amp Male Adapter. The one listed below will work.
Camco 55165 RV 12" PowerGrip Dogbone Electrical Adapter with Handle
Now you can plug your RVs 50 amp cord into the 50 Amp to 30 Amp adapter and plug the other end of the adapter into the 30 Amp to 15 Amp Adapter and plug that adapter into your home electric or a 15 Amp extension cord.
Once you have installed the three-prong adapter on the power cord from the Motorhome it is time to plug it in.
Here are the steps to take the first time you plugin.
1. Make sure all electrical appliances in the Motorhome are turned off.
2. Turn off the breaker on the house circuit you are using.
3. Plug the Motorhome electric cord into the house receptacle you have chosen.
4. Reset the house circuit breaker, you should now have electric to the Motorhome. If the circuit breaker goes off again, double-check to make sure that all electrical appliances in the Motorhome are turned off.Special Note:
If for some reason the power cord on the RV does not reach the receptacle you are going to plug into on the house, you may want to use an extension cord. If this is the case, it is important to understand that you cannot just use any extension cord that
you buy at a hardware store.
The extension cord should be at least a 10 Gauge Vinyl Outdoor Extension Cord
and should be just long enough to reach the receptacle you are plugging into. Using a longer extension cord can create more heat and also becomes more inefficient.Limitations On Running Appliances
First understand that the circuit or plug you are using may have other plugs on it as well. If the circuit you are using is a 15 amp circuit, it means that the total amps on that circuit cannot be greater than 15 amps or the breaker will trip. So you may not actually have 15 amps available to you depending on what else is operating off of that circuit.
So, just because you are now plugged in, does not mean you can run all of the electrical appliances at one time like you could if you were hooked up at a campground or RV Park. You have to limit your usage to be below the 15 Amp limit for the circuit you are hooked up to. If you exceed the amperage limit you will continually trip the house circuit breaker.
Here are some Amp usage numbers for common electrical items found in an RV.

These appliances should not be run at the same time or you will trip the circuit breaker;
Roof Air Conditioner, Hair Dryer, Microwave, Toaster or Toaster Oven.OK To Run Together
These appliances can be run safely together, TV, DVD, Laptop Computer and RV Refrigerator.
If you are not sure how many amps an appliance uses here is a simple formula to determine amps.
Divide the Watts by the Volts and that will give you the Amps for that appliance.
I hope this helps.
