I had SMB-W include a Lagun table as part of Starr's build and they installed its mount plate at the passenger side of the rear sofa:
I like and use the table in that rear location, but I have found (as others have) that I would also like a table for the front passenger seat when it is rotated to the rear. One reason is that I often leave the sofa down when traveling alone (i.e., don't "make" the bed during the day). I also personally often find the front passenger seat more comfortable than the sofa.
My design goals for a front table were (in decreasing priority):
a) Have the table be comfortable for keyboarding and mousing a laptop computer (primarily for photo editing);
b) Make my existing Lagun table also mountable in the front (to avoid having to store a 2nd table+hardware);
c) Avoid congestion in the passageway between the driver and passenger seats by the table and its mounting(s), both when the table was installed/mounted and when stored.
I found 86Scotty's front-mounted-Lagun solution (link
) attractive, but thought that it might be even easier to mount the Lagun "wall bracket" to the seat's base rather than the sliding door's front pillar. After convincing myself that it was workable solution, I installed a custom bracket and have been pleased with the result:
