With enough ingenuity, you should be able to make one of the current Bulldog bodies fit most new-gen truggies including the Jammin( I think ).
Personally, I like all these new cab-forward designs. I like having the option of running one. Many people don't like them, and they don't have to buy them, they can keep running what they think looks 'right', but having them available for those of us who want them is certainly nice though.
