I have wanted a travel trailer for years and we are ready to buy one soon. A few years ago, I asked some question on this board and everyone was so helpful and I learned a lot so I thought I would ask here to make sure I am figuring things out correctly. We are looking at a 233s rockwood roo. 4531 Dry weight, gross weight about 6331 lbs. We own a 2004 passenger Chevy Express 2500 V8 6L, 135 wheel base, 3.73 axle, automatic...after looking it up I figured it has a 7900 lb tow capacity. We had uhaul install a hitch back in 2005 but most stickers are missing and we misplaced the paperwork. But there is a sticker 78144 on it. After looking up that part number, I think the hitch is a class 3 with 5000 lbs max weight and 7500 max weight distribution. So if we get a weight distribution hitch for the trailer, are we good to go? Am I missing anything? Thank you for anyone willing to review this for me! We have 8 kids and have taken multiple trips to Disney using free dining but if we buy this trailer I plan to FINALLY get to the Fort!
