I was looking for the same kind of measurements when I was vehicle shopping. Everyone mentions cubic feet of cargo space but all I wanted to know was measurements for hauling and camping.
I finally got around to doing some rudimentary measurements today (not perfect but you get the general idea). Here’s some photos of various seat configurations. In all of the photos, the seats on the passenger side are slid forward to get the most length behind them. If anyone sees something that looks off or would like additional measurements, please let me know and I’ll edit the photos.
