I've never had moisture under my bed with the Northstar. I guess due to all the underbed storage. The bed's all made and ready to use.
Find yourself a used Northstar. Well built,roomy and plenty of storage and a 6-8" coil spring mattress. Reflectix works pretty well as an insulator and slips under the bed flat.I like the idea of a hard side pop up and am surprised more truck camper manufactures don't build them however I am not all that impressed with the Alaskan interior.
Hallmark has raised the prices on their truck campers. $44000 for a standard pop up truck camper is way too much. I may have to look at either a Phoenix or an Outfitter. I am also open to buying used.
