Alaskan Campers are hard-sided pop-up slide-in campers made in the U.S. for the past 50 years. This one is matched to a 1-ton Ford F350 4×4 utility bed pickup. The roof raises hydraulically to provide interior standing room while camping.
There is an excellent review of these campers with many photos at Truck Camper Magazine. Here are a couple photos from the article showing the raised position.
