There is a lot that goes with trailers. You will need to study your local and state laws and figure out what pertains to your use. Business is different than personal use in my state and business use changes when you cross state lines. By all means get a gooseneck to haul equipment with, just pay attention and get a good one. Lots of cheap junk out there. You get what you pay for. Look and see what the construction people use and ask them what they think of what they are using. These people can destroy a trailer in the first year.
