We are taking our first RV on a 2400 mile trip this summer, and we plan on towing our '05 Suburban, which is 4WD and towable. It has a curb weight of 5500 lbs. Our coach is an '03 Itasca Suncruiser with a Ford V10. I recently weighted it on truck scaled fully loaded with fuel and fresh water at a little under 19000 lbs. The GCVW is 26000 lbs, which will accomodate our Suburban, but is toward the outer limit. I'd prefer to tow something lighter, but don't want to buy another vehicle now. I would appreciate hearing from anyone who has towed a similar rig or from anyone with thoughts or guidance on the matter. Thanks.
