I'm tearing up my hitch...Help!

Equalizing hitch! The coach is nose high, an equalizing hitch will level out the coach and the trailer, raising the clearance at the hitch.

simple to me, ether a drop down bar or turn the dropdown bar over. works for me, now its all happy-camping

Don't even look like taller tires will fit on the trailer. Intheburbs is correct.
In the first pic the angle of the trailer looks right. I would try switching out the jack for a swing away one like was mentioned.
That trailer does sit low to the ground.
As it is even if you raise the rear of the rv or the hitch the rear of the trailer will just get lower. It's all geometry.

This seems to be the only viable option.

Unfortunately, you're fighting physics. Your hitch is so far rearward from your rear axle that any motion from bumps or undulation is magnified/amplified.

Looks like you have an adapter then the hitch. Why don't you just get the proper drop hitch. Then the hitch will be much closer to the RV and less chance of dragging.

Looks like you have a 2" drop hitch and the "adapter" drops it another 4". So, if the 2" drop was dragging the trailer, tey a 4 inch drop. If that doesn't work, try a 6" drop.

Not a expert on this. But some have put axle on bottom of springs instead of top. Flip my axle video.
It's not as simple as putting axle on bottom of springs. Need to install new spring saddles on top of axle. May also need to do some wiring for brakes.

remove the jack and install a swing away hitch jack.if you raise trailer you will also raise center of gravity

Thanks for your quick reply Ron. The adapter is not moving, it's in there tight. The problem is that whenever I go over any uneven surface, the bottom of my hitch post, scrapes the road and send sparks flying. How can I adjust the overall ground clearance of my cargo trailer so it sits higher? And is that the only option?

Welcome to RV.NET.

How much drop did you get to level out your trailer? You may need a clamp to stop movement of adapter.
