I need some dump trailers for my business. Where might these trailers be purchased?
You need to get a hitch for the truck first. After you have the correct hitch, you need to also get the rest of the towing equipment such as sway bars, lights, and safety chains.
That depends on the size of the tractor trailers (they come in different sizes/models). and how many roadways you will need to get them on/off the land.
