Thanks Dan,The color latches are for just that.
Tom, The entire trailer is built around
1 The wet saw station. i built the splash guard (bulkhead) with 1" clearance when the wet saw table is fully under the blade, and 1" in front of the doors when stored. i also put in a 2"lip from the across the open area. Then I had Line X waterproof the entire back area. the saw is mounted on a steel box with with a 10 gal rough tote water tank under it. (i can drop a heater in there for when it gets cold (I do run anti freeze to keep the lines clear) all I have to do to cut, 13" and less, is plug in the trailer.
2 The Rubbermaid big wheel. I use 18 gal totes for trash, mortar and whatever, the big wheel can haul systainers, totes, material and even the wet saw to remote areas quickly, it is 32" wide and will fit in 36" doorways no problem. It hangs on the left wall right across from the door (and can be in or out in a min) my grout bucket and ProKnees sit below it.
3 The sys racks. ( I will give a short rundown on making them in a different post) The one by the door is for my most used kits and has the compressor on top. Shifting to the SYStem ;D allows me to pack so much into a small space and have what I need at hand. The Key to this concept is the notion of a KIT. Everything you need for a task is in the kit. If you need a single tool in many kits either Keep it with your screw kit (as you will almost always have that one with you) or just have several copies of that tool, This way you have what you need to complete your task when you grab the kit.
