Forget it you're not going to tow a trailer big enough for 5 with a crossover. I've got a half ton truck with almost 1,700 pounds of cargo capacity and I'm nearly maxed out with 5 of us in the truck hauling a 3,000 dry/3,600 GVWR trailer. An SUV with 5 people in it is going to be massively overloaded with a similar setup. Your best bet is to find a popup with the lowest tongue weight you can (many of the bigger high sided popups are actually heavier on the tongue than some light hard sided trailers) or upgrade to a crew cab pickup (from experience I'd say a 3/4 ton or at the very least an F150 with the HD payload option). The only other option I could see would be two vehicles, one to haul people and gear and the other to tow the trailer.
