well i was just told some info i thought i would share with everyone. so i went in to get my trailer back after having the wheel bearings greased. i know but i just had no time to do it on matter how easy it is. so the dealer told me that anything over half the weight of the tow vehicle needs to have a weight distribution hitch for it. i was always under the thought that #5000 pounds or more needed a WD hitch. but its is safer to use one when ever you get to or over half of vehicle doing the towing. and i also learned that you should check the distance between the wheels and finder before the trailer is hooked up then set the hitch to it with in half of a inch + or - of that unloaded height. if you know this or have heard this before disregard but i have never heard this.
