Been fulltiming almost 4 years. Early on met another fulltimer towing a big fiver with a MDT, and he had spent his whole career in trucking. I asked his advice re medium-long term parking. He told me it's an important two step process: 1) when you arrive, shut off the engine. 2) just before you leave, start the engine. That's it, he said-- with reasonable care these things are virtually bulletproof. I've followed his advice and had nary a problem with my Cat starting.
