suburban as a tv for first tme

Thanks for the responses. To answer some of the questions: no my pu doesn't have a bench seat in the front so we can only carry five with driver. Our grandkids are all under the age of 11 so their little bodies aren't going to add much wt. maybe 225 lbs total. Yes I would love to find a 3/4 ton suburban to rent but they are hard to come by. I've checked with all our local rent-a-car dealers and none will rent a tv, insurance reasons I guess. We will only be gone 5 days so don't need a pile of stuff. The campground has full hookups so wont carry extra water or waste when traveling.I would love to hear from someone that has towed with a suburban or similar vehicle. Thanks again for weighing in.
