The Gladiator is definitely not a crossover. It's a true body on frame truck.Family of 4? Get a Wrangler, or better yet, keep the one you have, and buy a real pickup. Dont get the Gladiator, because it is new, and a crossover vehicle. If you only have one vehicle, what are you to do, when your First Year Gladiator breaks down?
That said, suggest the OP get a full-size pickup based on his stated criteria.
