AAA will tow you to where you want. GoodSam tows you to the nearest authorized service center that they are affiliated with.
How do I know? I have both AAA for the car and GSRA for the RV, which also covers the tow vehicle. Anyway, The truck broke down when backing up the driveway. I thought this would be a good time to check out my new GSRA account. I called them and they said the nearest service center to my home was a Midas muffler. I told them my service guy was 5 miles further up the road and could I pay the difference to have it towed there. She said no, they only tow to there authorized locations (read kickback). So I called AAA and they said no problem, we will tow it wherever you want and if it is beyond your miles you pay the difference.
As soon as my GSRA runs out I will look at AAA RV and compare it to Coachnet.
