Noob here, with a similar question. The last time I was in a truck camper, it was 1972, so I assume a lot has changed.
Looking at retirement plans and so far when it comes to full-time RVing, the only thing I've totally decided AGAINST is a 5th wheel. I'm prefering the motor coaches, but from what I've been reading, those can sometimes limit where I go due to length. Which has led me to truck campers.
Can one full-time in these?? Emphasis on "one". LOL Oddly enough, I was looking at the same Arctic Fox campers and also wondering what kind of truck I'd need to have.
