Fuel on up-wing tank. Not fullest.
With strong crosswind, and steep bank angle there is a serious risk of fuel starvation due to un-porting if you are on the low wing tank. So the fullest tank rule isn't always a good idea.
Prop will stop going over the fence, and you are left with a dead stick landing in a high-pucker situation.
Ask me how I know! ( But maybe the best Xwind landing I've ever made )
