A bit of a unique project I built for my own family right around the time our first son was born. When he was four months old we got plenty of use out of it on a five week road trip through the Yukon and Alaska.
It was built with standard framing (two by sixes ripped in half). The cavities between the framing are filled with two and a half inch rigid foam that was spray foamed in place and then the entire structure was sheathed in one inch foam making it an extremely well insulated camper (R-17.5+). The exterior siding is quarter inch fir plywood with v-grooves cut for a tongue and groove look, many of coats of primer and paint and all trimmed out with cedar. The interior is tongue and groove pine and the roof is a single sheet of EPDM rubber with a 40 to 50 year lifespan. There are three windows (two that open) and a roof vent to allow plenty of airflow on warm nights.
The section extending above the truck cab provides a lot of storage while the folding table in the main section quickly collapses and converts it into a sleeping platform. An exterior plug allows the camper to be hooked into an external power source to power interior outlets. One of the interior outlets is controlled by a thermostat allowing a small personal desk heater to go on and off as needed, which is not all that often, even in negative temperatures.
Weighing a total of just 1248 lbs it can be moved in and out of a pickup truck with the help of a friend or two.
