In my extensive research as the resident "Trekker Expert"
I have seen the aforementioned "longbed" Trekker.
In fact he has a website devoted to the Trekker and how he converted a shortbed into a longbed version. If I remember correctly he is based out of the PNW (Idaho?) and the pics above are when he shipped the shell to Texas to be made into a mold for future duplication. Truth be told, he is the true "Trekker Expert" whereas I am the "Trekker Wanabe"
