OK, maybe this should go into the "dumb things you have done thread". The front struts didn't work as mounted. By placing the mounts as far apart vertically as possible to maximize their lifting strength, I ran into some crazy geometry. If you measure the 19.75" in the closed position and install (like I did for the rear) then the shocks are not long enough when fully extended to allow the roof to go all the way up. If you mount them so that the roof can go all the way up, there may be less than 19.5" between the mounts, which means the roof can't go all the way down.
Ask me how I know, I dare you.
There is a reason FWC puts the lower mounts about 2" up from the bottom. The geometry then works much like it does on the back wall... with about 3" vertical separation between the mounts.
I re-positioned mine a few times, and checked lengths when up and down before drilling the 3rd set of holes. Check where that will put the holes on the inside by the mattress too. You want them to be below where the carpet attaches do you don't damage the lifting mechanism. Just sayin'
