Hey guys, soon I will be going to pick up a new OK Prowler Big Game II. My plan is just to use the bed of my truck (racks are not an option for me). I went out and did some measurments today and I will have a little over 4 feet hanging off the back (12.5ft kayak). Do yall think this is too much to hang off, I dont want the weight of the part hanging off to damage the hull. Any input is appreciated. Thanks.
