Howdy, I run car
tires on my 13'
Boler and it rides as good as my truck, and my truck rides like a large car, unless I`m on a highway with concrete break sections....normally towing it seems as if there is nothing attached to the truck.....I would weigh the trailer
axle and tongue and try 12-15 % of your trailer
weight on the tongue when you you load the trailer up.....as someone mentioned earlier, it sounds as if your tongue is too
light and bounces, lifting against your ball.....this will make a lot of noise, because the the hitch coupler has some play in it, unless you use an equalizer, and bouncing type action pulling up on your Element TV.....your trailer looks real good.....hopefully the under carriage is in the same shape......Benny
