As others have pointed out, the outdoor activities aren't that big a deal. It's homeowner shit that they're good for. Granted, I still think the full-size flagship models are pointless, mine's just a mid-size. I can transport small engine equipment (ride on mowers, snowblowers) that wouldn't fit in 99% of roofed vehicles. I can throw pavers, gravel, mulch, dirty tools, gas cans etc. in the bed without worrying about cleaning the interior or stuff getting into cracks, or noxious smells. All my plant waste from trimming and raking goes right in the bed and down to the local transfer station.

I had a spent oil jug crack in my SUV once and it took months for it not to smell like a mechanic's garage, not to mention the sludge stuck in corners that I literally could not get rid of and the permanent stain in the upholstery.
