I am using well nuts to hold down the panels. The reason I am waiting on pollen is for the eternabond tape that will hold down the cables. I realize that a little pollen probably will not matter for these, but why not wait. I am not in any hurry, and I wrenched my back two weeks ago and am waiting for it to get better.
As for the wiring.... I plan on running the wires down the the roof near the shower vent. From there under the kitchen sink, behind the fridge and come out to the controller that is mounted at the end of the cabinet. Wires from battery to controller run along bottom of trailer and come through floor behind fridge, then up to controller. This allows me to not have any of the cables visible.
