I almost had a trailer orded from Texas Truck and Trailer today, but I didn't because I wasn't aware on how much it was to get it registered etc. He said I would probably spend $115 after I bought the trailer and after tax. That put me up way too high so I decided to think it over and get on here and find out what all I need to do to drive a trailer legally. What do I need? I know I need to get the wiring for my truck (trailer will have it from factory of course) I will have a title, but I think he said I would have to have it transfured? What else? How much $?
