You should go with a satellite system. If you have say, Dish Network at home you can add on a receiver and put it in the truck for an extra 5 bucks a months. Regular monthly price is around $34.00 for the basic 60 channels.
You can buy 3 types of satellite dishes for a vehicle.
1.) A crank-up dish with a system on it to help you locate the satellite.
2.) A semi-automatic system that will automatically locate and lock on to the satellite when you are parked.
3.) A fully-automatic system that will automatically lock on to the satellite while you are driving or parked.

Approx. Antenna Prices
1.) $200
2.) $1000
3.) $1500 to 2000
There is a 4th option. You could use the same kind of dish that you mount on the house and buy a tripod for it and use it as a portable dish. I did this for many years while RVing. If you do this you will need a satellite finder/meter and it is a pain to set up and put away.
Find any Camping World and take a good look at your options.
