From what I can tell the Scouts have rubber flooring (which I love), but I haven't seen seat material specs.
I'd love to see a water resistant seating option in MGV (like the Bronco) or neoprene from the factory. I have neoprene covers on my truck, but it's just not the same as OEM options; almost all aftermarket seat covers look cheap to me.
As someone who surfs or mountain bikes almost daily, I'd like to have something resistant and easy-to-clean after regular exposure to water/mud/sand etc.
Factory roof racks for the Terra to carry something like a kayak or paddleboard would also be awesome; bed racks work, but a 13-14' kayak sits too far back when towing a travel trailer. This is another feature where aftermarket options are trumped by a rack that is securely built into the design.
Mountain bikers unite! I wish I was daily riding, but its more 1-3 times a week for me on avg throughout the year.
But yes, the frunk to handle all the sweaty/muddy gear (PNW rider here) without destroying the interior helps a lot, and then also the floormats being easy to clean (hose out-able?) and the upholstery something the can survive the mud/grime that people who live/enjoy recreating outdoors can attract seems important.
Also, another thought I had.
A "lightup the surrounding area" feature would be killer when rolling up to a camping area after dark/in the morning hours. Not huge floodlights, but anything helps when you're getting camp setup in the dark.
