This may be a dumb question, but...
How do you keep the wheels from hitting the fender support when there is a lot of weight in it? Will you put a bump-stop above the axle? It looks like there is only about 3" of clearance when it is sitting empty.
There is about 6'' of vertical travel before the tires can hit anything. The trailer will squat a little fully loaded but ill keep adding leafs to my spring pack to make sure even with a hard bump that it cant bottom out. If I have to add bump stops I will but I can see the need yet.
