Travel Trailer Towing Safety Concerns

Let me start by saying I am not the tow weight police or the guy that goes to the CAT scales to set up my truck and trailer, I do know the towing capacity of my truck and what the proper setup should look like. I took my longest trip yet with my tt this week, about 700 miles round trip to the beach and I saw some really dangerous tow setups. My first concern was at a rest area, I saw a lady towing a tt with a more than capable TV but the setup had the hitch head down almost to the ground and scraping the pavement and the front wheels of the truck barely touching the ground. The WDH used bars with chains and she was only on the first link. I offered to take it up a couple of links to try and level it out a little but she thought it was fine. I saw dozens of people with golf carts in the truck bed causing the trailer to be nose down and the truck to sit way up in the front. I also was passed by several people towing at 70+ mph weaving in and out of traffic. I guess I do not have a question here but I did not realize how many people knowingly or unknowingly put themselves and others in danger while towing a tt or fw . I usually frequent one campground all summer and I do not see this type of thing very often.
