I don't get it - why should it be any easier to push a pole than to directly
push the poptop? You're not getting leverage here.

:::Just a quick thought.
:::
:::How about a low tech approach.
:::An 8 ft. rod or pole (approximately) hinged in the middle. (work with
:::me here now - use your mind)
:::
:::One end is placed on the now unlatched mechanism up top and the other
:::end is placed on the floor, directly underneath the latch.
::: Of course, with the top down, and it being 8 feet long, the
:::'bent arm' is going to sticking out toward the rear seat.
:::Grab the hinge area and pull or push toward the front of the van
:::Bingo! up it goes.
::: Essentially you are creating a second arm like the one
:::already installed only this one is already almost open, giving better
:::mechanical leverage.
:::Your leverage is going to be better working on the horizontal where
:::you can put your weight behind the effort, than it is pushing upward
:::and carrying the entire load on your back and arm muscles.
::: The pole collapses/folds to 4 foot long and stores up above on
:::the bed.
:::
:::It's just a start but I'll do better after my 4 cups of coffee
:::tomorrow morning. ;-)
