Hello, campers.
On my recent trip to Northern California I tried out a couple new gadgets that might be of interest. The first was a new Rubbermaid 14 Can Briefcase cooler. The advantage is that it is slim enough to sit on the floor behind either you or a shortish passenger, without having to sit on the seats. It is also easier to get into the plane, if you are bringing it in through the door, as the pilot seat doesn't take as much messing with to get it into the back seats. The negative, however, was I found myself moving it onto my seats anyway, as I couldn't put my seats back enough when in cruise. For takeoff and small flights, where I don't need to move my seats back, it would probably work. I also think that it could be a candidate for making it into a custom air conditioning unit due to the cupholder indents, which could be cut out, and the option of just having it behind your seats until you level off.
The second new gadget was the Coleman 6 person Instant Tent. Positives: This thing really is instant. It took my wife and I about 30 seconds to put it up. Here's a video of people doing just that:
Taking it down is just as fast, and putting in and removing stakes takes additional time. Negatives: I had to remove the back seats to have the space to lay it down. You could probaly get it in by having it partially in the hat rack over over the back seats, but results would vary by model of plane. I have the easily removable back seats, so it wasn't much of an issue. The tent is also about five pounds heavier than my old one, but I can now stand up.
Hope that helps!
