Without doing a whole engineering analysis we can go by history and experience. The majority of the "fleet" keeps the doors closed with no ill effects. It does not seem to affect the torsion bar adjustment. The main problem appears to be the limited lifetime of the struts which affects the adjustment and leaving the doors open "may" help in that case. An alternative could be to remove the struts and close the doors for long-term storage. IMHO it is safest to keep the doors closed. Keeps the inside cleaner, no animals can get in, and you can put a cover over the car. I DO recomend a small piece of rubber between the rear hinge and the torsion bar so the bar cannot rub and get scratched by the rear hinge.
