Access cab is great for just me and a passenger. I keep my rear seats folded down and my gear in the backseat. Two toolkits, battery jump starter, tow strap, jackets, towels, a little water/food depending on what I'm doing, the laptops, ect. I'll get pics tommrow. I mostly consider my truck a two seater with a trunk and a bed. I use the backseat for people usually every weekend though... Usually its just me and two girls so room isn't too bad.
The longest trip I've made in my access cab with people in the back was from Ocala to Daytona... and then back four hours later (with us leaving for Daytona at 10PM, hahahaah). It wasn't comfortable for four adults but it worked cause it had to. Everyone fell asleep on the ride back (with the exception of me of course) but that also could have been because we had all worked a 10 construction shift earlier that day.. Nothing like getting off work and deciding to go to spring break
