I have used every size and type of trailer there is at one time or another. The trailer that I try to keep hooked to my truck (2002 Chevy 1500HD) at all times is a 18' CargoMate enclsed. I have every tool that I might possibly need at my disposal on every job. Everything has a place on the trailer, stays dry and secure. I bought my trailer because I live in a condo with no storage, but I think they are the only way to go now. Make the investment and purchase a trailer. You won't know how you lived without one. There are ways to do all of your equipment racks like mine and save ALOT of money. Tires and brakes aren't a "issue" they are "maintanence" which as long as you are making money will be no big deal. My tailer empty weighs around 3200# with the boxes and racks and the only thing I would change is I wish it were bigger.
