ive recently (6 months ago) finnished my series on a cut down rrc chassis, traybacked, tube front etc for trialling and hopefully challenge events late on, but i wouldent do it to a road going truck, stick some parabolics on it, a 200tdi on a series box with overdrive, rangy diffs etc, yould end up with something that drives alot like a defender but isstill a series, with series charecter, thats what i would do if it had to go on the road
