Welcome to the Lagun revolution. I have mine in hand and look forward to installing it when I get my new trailer in 34 day, 3 hours, and 40 minutes.
There is a long thread with Lagun installs and how different people provided the needed support. Your methods would be a great addition to the collective knowledge base.
BTW I love your color choices. The Lagun really completes it with the unobstructed view. Not to mention not having to get your feet around anything on the floor.
