People use truck campers for different things. Parking it in the woods and staying outside isn’t the only right way to use one.
I used mine as my home base at Burning Man, in the middle of a desert. I needed to be able to pull a 10,000 trailer also, so a camper on a dually made sense.
I hung out inside quite a bit, escaping the dust storms and daytime desert heat and went out more at night. Personally I think anyone who makes a big deal about being a real camper in the woods but brings an RV is slightly contradicting themselves.
