Having had a bottle jack go over and deposit a landy on me (fortunately not fatally) I'm pretty paranoid about getting under vehicles without stands these days, too.
mostly use a decent-sized trolley jack and then stands under the axles, unless I need the axles free. I have been known to attach the engine hoist to the front bumper of the 110 in order to change the front springs; but that doesn't involve getting underneath.
