I have had both GS and Coach Net. And CN is by far the more competent. They have service techs available to help over the phone.
GS often doesn't seem to even know the difference between a Teardrop trailer and a 40' Class A.
Neither service is perfect of course but I'll stay with CN after having experience with both.
As far as AAA? I've read so many complaints about them I wouldn't even consider their service. The biggest complaint is spotty service coverage and service times. Leaving motorists stranded overnight for instance.
