Now that the electrical questions appear to be answered let's move to tow vehicle.
Quite honestly unless you have to have a third row seating a truck with a tonneau cover or bed cap will be much better suited/designed to tow a RV.
Pay NO attention to dry weights or max tow weights of the vehicle. Use GVWR of trailer for calculations & the numbers from the drivers door jamb of the particular vehicle. This will prevent a costly mistake that a lot of us have made in the past.
