What's this hole for on the H19

[Rusty]

Does it have anything to do with proping up the sliding hatch?

Pop Top Cabin Enclosure

The ends of the aft brace go into each hole on the sides of the slider track.I have one on our H260, works well.

Those are for the Camper Top

There is an aluminum tube that holds the front edge of the top and snaps hold down the edges. If you do not have the snaps you do not have the top. One may be available through the chandlery here on this site.

Looks like

where the support tube goes in for the camper canvas. Got one on each side right?
