As far as AAA, I keep a single AAA membership STRICTLY for the discounts at Disney. It is only $45 a year and pays for itself. We cover our cars and the camper with Good Sam ERS, so it may pay to get you another AAA membership.
I hear you and right now I have the AAA RV plus for the two of us and it runs close to $180/yr. I also got one year free of COACHNET with our new trailer and based on the good reviews of it I will renew it in Oct (approx $90/yr) and next Apr when my AAA expires, I'll drop that down to the basic membership just for me so my total costs for both will be less than $140 for both.
