I have a 2011 Rockwood 232 Tent Trailer and need to replace the handle on the trailer jack. It's a top wind style jack. There are, apparently, four brands--Atwood, Shelby, Fulton and Dutton. Does anybody know what kind of jack is used on these trailers? I don't have ready access to my trailer right now as it's in storage, otherwise I would just look at it. Thanks for the help.
