Can someone explain to me everyones fascination with only pulling 75 to 80% of the recommended tow weight? I can understand if thats the boat and trailers dry weight it leaves you room for fuel and toys and other gear but limiting everything to that. I know it pays to be safe but I think I trust an engineers ratings especially these days when they factor in a safety margin because of the sue happy nature of the nation. Just on a hunch I had a relative of mine who all though he doesnt work for the auto industry but who deals with a lot of their engineers, ask them. They confirmed my suspicions when almost all of the new vehicles are rated they are under rated to prevent the average moron from hurting people when they figure well hell a few more lbs wont hurt. I know its good to be safe but after reading alot of these posts Im beginning to think half of you work in the aftermarket towing parts business. I know for alot of the old timers that these upgrades were necessary on their older machines. But for any full size truck newer than ten years old about the only upgrade you might need is a tranny cooler and most dont. Now I am talking about your average post author who is pulling around 4k to 5k lbs. So words of advice to those who wonder about their trucks if its not fullsize with a strong v8 and solid tranny THEN DONT. If it is and you still have questions go to a dealership where they can tell you exactly whats on your truck. Your average V8 powered full size will easily pull upto 5K with the right hitch and brake setup
