I want to store a W123 for six months, maybe more. Do diesels require any special storage procedures over gassers?

What would you do to store your diesel? What precautions would you take aside from battery removal, to ensure trouble free restarting in the spring, and to prevent the ingress of moisture, insects or rodents? (mice destroyed the headliner and carpets of a 66' Dodge Charger I once owned and stored for a few years. Hornets moved into the glove compartment of a 55 Chev Sedan Delivery - very horrible and painful suprise)

I doubt I will use a tarp, but will use a sunshield to save the dash. (I had a 240Z Datsun uncovered after a winter under a tarp to reveal big blisters of moisture had bubbled up my nice new Iberian Red paint job)
I have had a few Storage Disasters, and wish to avoid more.
