Here is perhaps a little help .... Go to www.antennaweb.com
on the internet, put in the address of the campground locatons (you don't have to be exact) it will tell you the local channels, the distance and the compas heading for the transmitters... If you don't have the interneet on the road or a smart phone you could always do it before you leave for a specific location your headed ... it's a great tool..
We just purchased a 2013 26RKS and hope to get it in 6 weeks.. I'm sure I will make some of the same mistakes as we start out.. but hopefully my tip on Antennaweb.com might be of some help down the road..
And on that note.. rather than gooing for the technology package I am going to pick up a 26" TV for the Bedroom and either a 26 or larger for the front room... lots of choices .. now the fun begins as we ready for our unit to get here... By the Way, we are in Tennessee
