I'd guess most 2 horse steel trailers weigh about 2500 pounds to start...minimum.
When my father was helping me get a truck to pull my steel 2 horse trailer 3 years ago he was going to get me a Chevy 1500. I told him it was not big enough for the job. My 2 horse steel horse trailer weighs 6500 lbs EMPTY. Then I had to add the weight of the horses, etc, etc, etc. Steel Trailers are really heavy.
My brother in law (car salesman) told him I needed a much bigger truck also. So I ended up getting a 1989 Ford F-250 Stick Shift. Not my first choice in trucks (I wanted automatic even though I know sticks are better for pulling, and I wanted a King Cab) But I was given the truck and all I had to do was buy the towing package and break/light hook up. So I can't complain.
