The 310's biggest "gotcha" is the fuel system-six tanks to manage, and a complex cross-feed system.
I remember re-fuelling one after she had come out of the shop for tank maintenance (all tanks were emptied beforehand), and they asked for her to be topped up, it was over 160 gallons. In addition, because it had tip tanks, those had to be filled last...
It is a wonderful-flying plane, however, and it feels as sturdy as a tank.
