We have our Carryout GM1518 for a couple years. It has worked very good.
I recently bought the tripod base. We were at a location with heavy rain and water run off. I didn't feel comfortable with the dish being directly on the ground.
We use a standard receiver from the house. We do not care whether we get our home stations.
I installed a new coaxial cable and power connection under the hood with easy access. We leave our power connected all the time since our programming requires the dish to change satellites when necessary.
Yes your #10 wire with 20 amp fusing is good.
