You're right about the voltage drop being so very important, especially in lower voltage applications. I found this other website that lists the table values at '2% or less'. http://www.wiringproducts.com/automotive-wire . Before you start looking at one website for all the answers. It does not exist.
This website suggests shrink tubing over electrical crimp connectors, which if you use the typical heat shrink tubing, will result in trapping water under the heat shrink tubing, since heat shrink tubing is NOT waterproof! They make 'marine' grade heat shrink tube with hot melt adhesive added inside so it is indeed waterproof because of the hot melt.
They also suggest soldering crimp connectors as superior to crimp. It is not so! When you do solder a crimp connector, where the solder finally stops flowing up the wire away from the connector, it creates a 'hard' spot in the wire, where any vibration will cause the wire to repeatedly flex there and fail in a very short time. When you use a proper crimping tool, the flexing that is caused by vibration is spread out over a much wider distance.
