I have a Ram 2500 with an 8' bed but I'm not seeing many Grandby's but plenty of Hawk/Raven's around. I've seen a Hawk in an 8' bed but the ones I've seen they all have been mounted with the rear of the camper at the rear edge of the bed leaving a big gap between the cab and camper. My question is there any reason for mounting them that way rather than moving them all the way to the front of bed and have that gap be at the rear of the bed to carry more stuff?
