Default What is a "rear lift truss"?

Not necessarily. This rule seems to calls for consideration of the
chordwise lift distribution on the wing while the tail is low and the
relative wind is coming from behind. Under those circumstances, the
chordwise lift distribution will be biased towards the aft spars and
aft struts in a way that they'd never be exposed to in the (normal)
flight envelope.
