The strut on mine works fine, regardless of the angle. Now, I have never laid the H3 on its right side and see if the door will stay open!
In fact I really like the gas strut, since my wife has no trouble opening or closing the door. Closing the tail gate on our Bronco is pretty tough (and heavy) for petite people! I went to the beach last Saturday with a buddy who has an fj (beat to **** already by the way) and I noticed that they have the same configuration for the rear door except their strut has a little snap that allows you lock the extended strut into place so it won't close on you. I also noticed that if you do not lock it into place, even on level ground, that darn door will come back at you. Their may be a way to modify the H3 strut to lock in a way similiar to this. It may be as simple as making a notch in the extended strut and using a hose clamp or some other item to hold it extended.
I don't like leaving the doors open when I am camping anyway, all the bugs come inside and f@#K up my leather!!!
Regardless, park it on level ground when you camp!
