I have spent the last few hours looking for a kit to convert a single axle ton truck to a tandem axle truck. I want two live axles, not one live and one dead. Does anybody know if such a kit is even availabe for lite trucks. I have seen humvees that have been stretched and a extra axle added to the rear but dont know if they are both pulling or if one is pulling and the other dragging. Will listen to ideals also.
