The struts on my TT aren't the cheap ones you see most places. The normal struts used in automotive applications and on RVs to lift beds operate one way - they lift a given, predetermined weight. They rely on overcoming resistance or weight to operate smoothly.
Door struts are two-way. They push the door open then they dampen the swing at the end of their stroke. If you use a one-way, the door flies open and the strut bangs hard against the stops, straining the strut and the door hinges. You have to hang on to the door handle to control the opening speed. I replaced my strut with the correct one but I don't have the part number handy. IIRC, it was about $25 (plus shipping). The correct strut opens the door and slowly brings it to rest in the fully open position. I can open the door and turn it loose. The door opens quickly and smoothly then slows down as the strut extends fully.
