i'm sure the conversion has been done before from a traveller to pickup, as this is what a friend is doing making a light wieght pickup.
i was wondering how and where to add strengthening to the chassis.
We made a seperate chassis for our trav and after stripping down our other trav to a bare frame I would worry about the strength.
Have you considered a seperate chassis?
took us 6 evenings from steel to rolling with suspension.
