Your best bet is to use a metal tube mounted to the vehicle's chassis. I've actually been in powertrain design on a mid-engine vehicle with a front-mounted radiator that was a 4x4 for off-highway only use (hence my experience with difficult coolant purging). It used a steel tube weldment under the floor of the vehicle that was still up between the frame rails but the finned aluminum extrusion may work as well.

When I was in college I participated in FormulaSAE and weight reduction was a key goal. Just between the mid-engine and the sidepod radiator we found a couple pounds of weight savings by using rubber hoses only for bends and flex couplers, and using steel thin-wall tube for straight runs. The metal tube is lighter AND more durable.
