Newbie here also. I joined Camping World in order to get the buying discount and through them I joined Good Sam for $1.00. So far, other than junk mail offering insurance, I haven't gotten much out of it. Although the monthly magazine has some good info. There are RV parks that offer discounts to members also, but again, I haven't had a chance to take advantage of any them.
On the other hand, it was only a buck.
