I helped in a patent legal fight once. Best you can do is try to get a share of their profits and/or enjoin them from selling it. It becomes a battle between the expert engineers which costs a small fortune. Too easy to lose so no contingency fees. You have to be well endowed to enforce your patent. Bottom line is once the accountants have watered down their profits, your percentage of them (you don't get them all) won't be worth it.
Of course there is a big difference between inventing an anti-gravity device and some machineable part to modify and make a hitch work better. Someone will just re-engineer it anyway.
You can do patent searches online. You can get the stuff to file it yourself as well.
The key is in the marketing. Why spend $10,000 for a patent for some hitch modification that no one will buy or pay you a royalty on. Makes for a fun academic project for students but the fun and academic portion will be all its worth end the end.
Without giving it away, call and see if any manufacturers are interested. Most likely you can't get in the front door without spilling beans even with a confidentiality agreement. Just as well file your own paperwork first.
About everything I see at the store can be improved on or I see something else I wish walmart sold. But me marketing it is a totally different deal. Could search through patents and look for things to improve on which is what the big companies do. You file something and they will improve on your improvement.
