I have a 99 Ford Expedition 5.4 L with a max tow rating of 7,500 lbs. The GCWR is 13,000 lbs. I just bought a 2007 Surveyor 304 travel trailer that weighs 6560 dry with all options and dealer add ons. My expedition weighs 6,020 lbs with all my travel trailer goodies. IE sheets, blankets, chairs, silverware, everything that will go in my new travel trailer is in my expedition. If I add my wife, kids and bikes the GCWR is 13,340 lbs. How significant is it being a little over (340 lbs) the GCWR for your tow vehicle? My expediton was full of gas when I weighed it too. I feel confident this is a very accurate weight assessment 13,340 lbs. I have thought about moving up to an Excursion, but I need some advice.
