I didn't see the voltage drop you mention, but did note that the unit's current draw is 7mA (which is less than my stereo head unit even with face plate off). I don't have any problems with the gauge of wire used, my westy does not have a very demanding electrical power requirement when camping. Lights are LEDs, back of fridge fan I have is less than 1A, the water pump is intermittent 2.5A, I guess the stereo is the biggest constant draw, but I'm guessing it is 5A or less most times. alistair
