Glad your keeping the old girl busy.
Generally it's not a great idea to leave something with a load overnight. I've never been around a crane that's not gonna creak and settle when left under a load for an extended period of time.
For a 1 man crane company a 50t isn't a bad size. Here in the states you would have to haul the cw separately, so you don't see many 1 man crews with a 50t. If you can leave the cw on the crane and just roll with it, the cost of operating it isn't gonna be much if any less then running a smaller crane.
