Query: good, but needs more work

I have a truck-camper and needed to tow a little trailer behind. The camper reaches 40 inches behind the original truck hitch. Because I couldn't find a 36/40 inch hitch extender, I bought this tube, went to our local metal shop, bought a 1ft 2x2x1/4inch metal for $8 and went to our local welding shop. They welded the 2x2 inside the 36inch receiver and drilled a 5/8th hole in it. Now I have a fully workable 40inch hitch extension that worked great on our trip from FL to NY and back.The only thing I didn't like a the receiver tube was the heavy fin inside the tube. This fin/barb I had to remove first in order to slide my 2x2 inside. This wasn't an easy job. But at the end I have a hitch extension I wasn't able to find anywhere out there.
