We use our tailgate with our satellite dish and pointing and is very easy. No need to spend the money for the "tailgater". Buy a satellite meter (you can get one on ebay for under $20). You don't want to point using the meter on the dish box. Set your approximate elevation at home (if you live close to the stadium, check your current dish and use that same elevation). I'm assuming you'll be buying a generator (Honda and Yamaha make great, quiet, 1000 watt generators, more power than you need for tailgating). So, you'll set up your box, connect to TV, run coax to dish. On the dish, use a 3 foot cable running from the dish. Turn on your generator, attach the coax from the box to your meter, and the coax from your satellite to the other input (they are marked on the meter). Move from right to left or left to right, you should find three signals. Focus on the middle signal. You should be good to go. Once you set it up once, you won't need to adjust again. Lastly, connect the 3 foot coax from the dish to the coax from the box using a connector. I have to run checkswitch on mine because I have a switch at home, you may not need to.
We take ours to UCLA games, and it takes us literally 30 seconds or less to find the satellites.
One last tip. Whenever we take it to a road game, I use Google earth to determine where south is in relation to the stadium. Compasses don't seem to work well when you are surrounded by cars....
