Let me throw out an idea that has been churning in my head for a while. After I make a confession. Confession first: When I decided that some areas were so remote that I needed to camp to not spend half of my life going back and forth to a research area, I researched and found a small hard sided pop up trailer. Alpine Expedition, well equipped, high clearance, intended for back country camping, and 20 + grand. It only weighs 2058 lbs so can be towed by a smaller vehicle. I have camped in it but have not done remote off road camping. I might if I had research partners. After some of my later experiences with BF, the thought of being solo in the remote woods at night with resident BF who might not want me there is terrifying to me. OK I am a chicken! But I have heard an adult BF coming right at me. Just the thought of taking a trailer down some logging roads I use where you have to go miles just to turn the truck around only gets worse when I think of needed to turn around pulling a trailer. These are for the most part one lane roads. You meet a logging truck going the other way and you are the one they expect to get out of the way. I have ended up backing up for a long ways.
On the other hand it would be good to have some sort of sleeping arrangement in the back of my truck should I choose to. Camper is too heavy and unstable. Camper shell is better but sleeping in one is a problem due to the 6.5 foot bed and low height. Looking at my pop up camper there has to be a way to get some sort of thing that pops up in the back of the bed of the truck and when under way is folded down flat like my trailer does. Hard sided is heavy and some campers like that exist already. TV commercials tout some latex products that are water proof. How about a coated canvas cover, over a light wood frame, that normally rides flat in the back of the truck allowing visibility out the back window? When you want it up, you fold up a covered wagon type hoop frame that makes a roomy waterproof shelter in the back of the truck. Could even have windows. No ropes, ground cloth, rain flys, or dealing with a wet tent that usually manages to leak. Anyway I doubt I will ever make the thing but some clever and tool handy person might for the fraction of the price of a pop up trailer or in the bed camper.
I have seen those Norseman. Think Subaru has one for their vehicles. It is pretty handy for BF. It does not even need to stoop over to mess with you. Can look straight in. That cannot be good for the top of your truck.
