I'm late to noticing this posting as I had no interest in a Lagun Table.
But,
I have modified the existing table mount in our 2015 FWC Flatbed Hawk. I took these pictures back in July 2019 to share but did not follow through.
I wrestled with the table slipping down and trying to find just the right friction for the two knobs to make it work. Really a no go! If you have the table too high you have a risk that the table will break the window glass if it is allowed to swing while driving ruff roads.
I had some left over 1 1/2" electrical conduit I noticed and it would slide over the table tube. Perfect! For the the two tubes I cut to length for where I wanted the table height to be for our needs. The long bottom tube length just needed to be long enough where the friction that the table tube bend starts would prevent the table from dropping lower. Kind of what FAW3 did but longer length and no drilling.
The upper section of table tube just needed a spacer with a notch out for the welds so the table stays at the height and the PVC adds lubrication for pivot.
Now that those two sections were added I adjusted the clamping knobs at just the right friction that allows the table to swing all around but stays in place.
We are happy with this modification and are able to use the table without swearing.
Cheers,
