I am looking at towing a 5er which has a dry weight of 10,258 LBS. According to my manual and data plate information my max tow weight is 13,700. My tow vehicle weighs 10,000 PDS. My GCWR is 25,300. The GVWR is 14,500. Vertical Tow Weight Rating (VTWR) is 3,425. I would not be loading out the trailer with anymore than 13,700 PDS. I haven't bought the toy hauler as of yet. I would like to get the forums advice to make sure that I've done my homework right before i actually make the purchase. The UVW of the 5er (curb weight) is 10,258. The toy is a HD Ultra Classic which weighs 900+. About 500 pounds of cargo weight will go in the trailer. It has a 100 gallon fresh water tank (800 LBS) for boon-docking. I won't be dragging that weight around except for when i'm boon-docking on public land or without water sources. The details of my truck, hitch and future trailer are in my signature block. If I buy the trailer based on the feedback which I get from this site I will be using the B&W hitch (found on their web site) chart/worksheet for determining my tow vehicle and trailer's actual weight using a public scale. B&W's web site has a great chart for all types of tow vehicles (2010 and up) and for all types of trailers. Thanks for helping out.
