2002 Toyota Tacoma Prerunner 3.4 pulling enclosed trailer

I run a mobile locksmith business for 16 years. I sold all my equipment and service van. I took three years off from locksmithing. I recently got the bug to start again part-time after my primary job. I am looking to get a 6x10 single axle trailer to pull behind my 2002 Tacoma Prerunner 3.4l automatic. Is there anything I need to add on the truck to help it out with the extra weight. I have pulled a boat and regular trailer with it before and it did fine. I would probably be pulling the enclosure trailer every day of the week. I don't plan on over loading the enclosed trailer it would be more of a mobile shop.

 

An equalizer hitch is a good addition along with a trailer brake controller and some firestone rear airbags.
