Thanks, I'll experiment with some different tires over the summer to see what works best... for the dually I think I'm going to use some WPL D-12 tires and wheels, they have an "off road" looking set. I ordered some and think they will work well, the next one I'll make sure I get the axles about 10mm or so closer.
The lift works pretty well it can dump a full load of dirt, but I wanted the servo to be able to "draw" it down but at a point it just buzzes.... I can live with it I just adj the end point til it stops...
