Gotcha............... The 5th Gen hitch design does not follow general frame mounting hitches typically used for a WDH. I don't suppose that means you couldn't do it. I read a few people have used a WDH hitch on the 5th gen with "no problems", but I think your skirting the edge of the design. I haven't looked into this toooo much though, hopefully someone will come along that has researched.
