Here is a picture describing what I meant.
I have some low cars bottoming out on the top angle. When I say low cars I am not talking about a Lamborghini, I had a kia optima, and a chevy uplander wheel chair van bottom out for example. Its not just height but wheel base that also can cause a vehicle to bottom out. I have a 2 inch lip welded on the insides I will be grinding them down about 2 feet in each direction from the top angle and hope it helps with the clearance.
I am considering finding some one to mod my trailer by getting rid of the 6" box holding the kingpin and welding the kingpin to the trailer and then flattening out a little bit more on the top and bottom angle and this trailer will be 100% perfect. Will the trailer be structurally compromised?
Other than this the trailer is solid. It drives very well, and feels very sturdy. All welds look good and apart from this little issue I have no complaints.
