Any modern wagon can handle anything from a paved road to gravel to a two track. I used to drive a pickup for work and I can count the times I put it into 4wd on one hand.
When you're not hauling the kayaks, you can haul people, pets, etc. Covered cargo and comfort.
FWIW though, if I needed and drove a pickup in the first place, I'd definitely make it my kayak hauler.
