My prior vehicular camping experience was in 1968
with a rented from the Newport Naval Base PX tent trailer towed by a Volvo 4 cylinder station wagon with a little dingy on the roof. The wife, our Toy Collie, and I drove to the Bay of Fundy area in Maine and had to stop to let the motor cool when we were stuck in Boston city traffic. What a neat experience on a camp site we had to ourselves. The huge tide swing was amazing.
We did a primitive tent camp out in September 2011 near the rim of the Grand Canyon, my first such event, with my wife's four daughters and a cast of many for a 30th birthday for her eldest. We cooked for about 20 folks all weekend. Along with the cold, the bathroom shovel arrangements were challenging for me.
We acquired the first Airstream (2013 25FB International Serenity) in October 2012 and had another camp out at the same location in September 2013 for her twin's 30th birthday and similar cooking endeavors. This was a much more pleasant experience, except for having to dig the truck out of the unseen mud. That was a real learning experience!
We decided to go for the full monty and took delivery of the 2014 Classic model 30 in January 2014. We have enjoyed both primitive and commercial camp sites. We prefer the more isolated sites.
Camping for us is anytime we are out of the house and sleeping in our Airstream, where ever we may be. We enjoy being out in Nature, but a warm bed sure is nice at night!
