I apologize for my somewhat confused earlier post.  I was referring to swap outs that Dometic recommends, and on their table listing those, there is no RM 4181.  But that is in the U.S.  And that is where I saw that they do not list a swap out for the 182, giving the information that I gave.  The closest equivalent in size is their 2183, but it still would not fit, and I take them at their word that the vent would not work.  

The table is here:  http://www.dometic.com/c17faeab-a5a2-436b-a032-b28317a7cff0.fodoc

perhaps someone less mechanically challenged than I am could find one that would be a close fit, and make it work.
