[Tigers] Tiger All Four Wheels Up?

[MAURO D'ANGELO]

Maybe I've led a really sheltered life, but I have only ever had a car on
jackstands one axle at a time (either front of the car or the rear).  I
think I read somewhere that you should not put both axles on stands at the
same time.  Is this true?  Is this dangerous?  Has anyone ever had a Tiger
on four jackstands at the same time?  Is that safe?  If this is possible,
what's the best way to do it?  Just curious.  Thanks.
