there are 2 points to this. 1 is how the trailer is designed to distribute weight when properly loaded. the balancing act between weight down on the hitch vs the weight on the wheels.
2 is, what constitues resonable risk. how much must a trailer manufacturer overbuild a trailer to be reasonably safe from litigation when some one misuses a trailer and it fails. the trailers have to be built to handle some over exertions due to user error. ie 40/60 so that the toungue is lifting the tail of the truck due to load shift during use. handeling a left side heavy trailer because some one has 1 full tank and 1 empty tank on the trailer with 2000lbs of liquid in the tank. the users tendancy's to not follow the weight or load specifications are part of the "proper" build process for a good trailer or any tool for that matter.

users view of the product also falls in to play as well. some one mentioned the in writing issue and how the manufacturer just replaced all the fronts in town. it is easier for them to not have to answer those questions then to find out. it also is better to make a product the user doesnt question right off the bat.
