I didn't read the whole post, so someone might have allready answered to this.
I see alot of pictures on here of little trucks that should NOT be towing a car trailer. It isn't if you have enough power or not. It is your GVW rating. technically all thos dekota's S10 jimmy's, exploreres are under weight so if you get into an axcident you insuranse could be VOID! and you are left with all the damages with you vehicles and the people involved including injury $$$$$$$$
You can tow a car on a trailer with a civic, but you shouldn't.
I have towed a car with a F 150, but techjicall I was over weight. If a DOT saw me, I could have been fined, and stoped right there with them not letting me go any further.
If it is a 3/4 ton or higher you are fine ( legally)
think of it this way. The law is one thing you want on your side, whet S$#* hits the fan!
