We used the Ready Camp Go Card for about 3 years before getting into Zone Camping (NE/SE). Usually getting the Gold Card ($199) because gives 60 day reservation capability. Zone camping is OK and well worth the fees, however, the "free" campgrounds are really weird. We have the NE/SE zones, yet we have campgrounds in CA, WI, IN & WA to make up the no. of eligible campgrounds. You can camp at other campgrds (Encore/ELS, etc) at a discounted rate (15-20%)but it still costs $40+/- per night depending on campgrd. To get more camps with Zone, you must upgrade to a full TT membership, which market price is $5000 +/-. Ready Camp Go has a better choice of campgrounds ALL OVER the USA, (Thou. Trails, Outworld, Encore, ELS, etc. - Same camps as a full 1000 Trails membership) and still only costs your initial fee, plus the $20+3=$23 per night. We're stuck for 2 more years of Zone, but next year plan to get another Ready Camp Go card to supplement. We had never had a problem with RCG getting into a campground w/EWS except around holidays, but that's expected.
