LEGO Technic 42209 - Mod - Rear Tow Mount Attachment

Recently I have been researching some different attachments for my LEGO Technic 42209 Volvo L120 Front End Loader. I have started to design some rear mounted attachments but firstly I needed to find a way to attach these to the L120. My goal was to build an attachment that required the least amount of changes to the standard L120 build (to make changing it back easier), while still providing a solid mounting point for my attachments and also looking good.

After looking at a few options, I came up with the below. The only change from "standard" is replacing 2 x 2L pins black with 2 x 3L pins blue, as can be seen circled in red below. These allow the beams to be attached to the chassis. A couple of pins were also used to attached it to the bottom beam. This will allow me to build various attachments but also easily swap it back to "standard" if I want.
