I just towed a 17c Jayco with ny 2012 Acadia, tow pacage and all. Trailer weights in loaded at about 3500, it towed well, I had the WD hotch setup to the instructions and kept the front end whereit should be. It towed well and made it up a 15 mile 5000 foot climb, but it was pushing it big time up the mountain, of cousre it was 105 degrees out when we started the climb! I will most likekly get my normal TV back up and running smoothly and not use the Acadia to tow with much. Did it work yes, for long distance, I wouldnt do it, and not with a trailer as big as you are talking about.
