As long as a guy only rolls the windows down, my pickup works surprisingly just like HECS. The critters just don't know what I am. So instead of blowing a grand on a HECS suit, just dropping me a case of beer and jumping in my truck might be a more financially viable option. OH, but keep in mind that "MY TRUCK" is the only truck that has this ability, so call me soon as spots are booking fast for the 2021 season. Thanks!!
