i have used a sangean ats606 in a dumptruck for a long time. thats rough
service! it even has knuckle marks in the speaker grill where i shifted
gears too hard with it hanging on the dashboard. that radio suffers
heat, dirt, vibration, an occasional drop to the floor and still works
great. if that radio cant stand up to your durability requirements then
you arent going to find one that will.
