Here is mine last summer. I built the trailer pretty quickly so we could use it on a cross country adventure before I left for Iraq. It is a M101A2 trailer with a commercial ARE utility cap. I found a adjustable ladder rack and cut some angle iron to make footings to attach it. A RTT is mounted on top but will be moved around for better use of the roof. It has a 30gal fresh water tank, hot water on demand and a external shower tent, portable stove, duel ac/dc freeze and fridge unit powered by duel optima top batteries that are maintained by 12v provided via the truck when running and solar panels when parked. led interior and exterior lighting. its was really slapped together but it performed fantastic and my son calls it the tree house. I will be working on it again when I get home in August for more adventures.
The top two pictures are my family's 1000 acre farm in Swan Valley Idaho and it was an amazing view that morning. The bottom picture was from out site at Grand Teton National Park. We were at the bottom of the loop next to this beautiful glacier melt lake and everyone would stop to check out the trailer and talk to us about it.
