I purchased a mobile home and it doesn't look like it has a ground wire. Can anyone make it suggestions on how I could fix this. Seems like this should be something I could do myself.

You can do this yourself, need to drive a 5/8" copper ground rod, then run #4 bare copper for the ground rod to the ground bar in your electrical panel, you also need to run this to your water service and gas service. make sure you get the right connectors. you will need to know the size of the waterpipe fittings, the clamp should be on the fitting. and the size of the gas pipe.
