I'm about to buy my 1st trailer and I have no clue about trailers! I know i'm going ot get a 5 x 10 trailer as my startup trailer with 2 wooden sides.. I have a dodge dakota and in the rear I saw the trailer tow weight was at 2,000lbs.. Is there anything I need to know before I go out and get a trailer? like for instance do I need to go buy a hitchball from home depot to install it? what about locks? more basic information would be appreciated!
