some interesting comments here.
10 percent tongue weight is a minimum. if you have a little too much tongue weight, your truck squats and you look dorky.
if you have not enough tongue weight, your trailer WILL someday start whipping on you coming down a hill and you will die or kill someone.
dorky, or dead?????? of those two choices, i look dorky.
how many lug nuts on your axles? if 5, then it is a 7k trailer, and i'd wonder if you are overloaded. if 6, then 10k, which is a big load, especially at highway speeds, especially with no equalizer. hopefully your trailer brakes work well????
it is a lot easier to make a taller back gate, and just load the wood further back on the trailer then it is to move the axles.
if it were me, i'd find a scale. weigh the truck empty. then hook up the trailer, and weigh just the truck again, and get your tongue weight. then weigh the trailer axles, and figure out your percentages.
