I bought a combination pintle hook (for lunette eye trailers) and ball trailer hitch, at a garage sale. It is a nice 8 ton rated thing and could be useful when I need to tow lunette trailers. It is also safer, in my opinion, when towing ball trailers because the pintle hook holds the trailer's tongue even if the internal holding mechanism of the tongue does not work for some reason.
I want to carry it along most of the time, the problem is that it sticks too far to the back and could get me in trouble when parking and backing into cars behind me.
My own idea is to make a little holder for it, a square tube that would be mounted on the side of the trailer hitch frame, pointing rightwards, below the truck. (instead of sticking behind, it would be below the truck)
Making one is not a big deal (already made half of it from steel angle), my question is what is a safe method of attaching it to the hitch frame. I would suppose that welding anything to the frame is a big no no for two reasons: 1) annealing metal and possibly reducting strength and 2) possible damage to truck electronics. Is that correct?
If so, then, can I drill, say, four 5/16" holes spaces about 3" in a "side" of the trailer hitch frame (that "side" is what looks like
3/16" or 1/4" steel plate) and just bolt this holder to the side with regular 5/16" bolts. Would that be "safe" with respect to the strength of the hitch frame?thanks
