Dodge Ram Mega Cab Long Box

Does anyone know of any plans or a photo of a Dodge Ram Mega Cab with a long box. My dad likes these trucks but he doesnt like short boxes. They are useless to him.

I tried to input that into dodges build site and it doesn't allow 8 foot beds on a mega cab....

I think they should make one.

yes I do too but there might be a length restriction that they aren't allowed I don't know. If you build something really long the turning radius is too big that might be the problem not sure though.

its the fact that the mega cab is already built on the quad cab long bed frame so in order for there to be a long box they need a new frame which = $

Last issue of Turbodiesel (subscribe at Turbodiesel.com) some purchased an 8' box, had frame cut and added too. If you own a cummins this publication
is about $40 per year for 4 quarterly issues but a very imformative tool.
