We *take* too much stuff.
It was ultimately the biggest death of our using the pop-up - the freakish oragami/jenga game loading and unloading (stuff out of the pup, stuff out of the truck, move this here, that there, and so on). Setup was a nightmare. We're over packers- always have been.
With the fifth wheel- we still have too much stuff but we have more places to store it.
As for setting up camp- it really depends on how long we'll be there. I like a minimal setup if it's just a weekend or long weekend. I like a lot more if we're there a week+.
It also depends if I'm actually off of work or not. Often times, I work from my camper- so I'm inside for 8+ hours per day. We treat the camper like a roving apartment and generally have minimal setup outside.
