we camp about 80 days a year as well ,we use a dish tailgater (349.95) and a vp211 receiver it adds about 6 bux a month to our bill I figure that's about a dollar a day
for gps I purchased a 7 in Magellan refurb at Walmart.com with lifetime updates for about a hundred dollars.
on the tail gater I seen one last week for 249 refurbed I think it was at ppl motorhomes
good luck and great camping in 2015
liven life in east TN and wherever my
