This is one of the reasons the TV news vans don't use masts
bigger than 52/56' on a Ford F-350 or Mercedes van chassis
and generally include "stabilizing jacks" at the rear corners
for the big masts. The few news vans built on minivan and/or
SUV chassis were generally limited to 25 to 30 foot masts.
