To be honest, for the most part, the reason we ask for the trunk dimensions are not for obtaining or calculating what the Fo may be per se for your particular build, no it is MUCH more simple than that.
When someone is willing to pay, I do indeed take into account and calculate everything, via the drivers, power, enclosure displacement, trunk volume, AND cabin volume, when a vehicle is brought to me, I can calculate nearly all and be DEAD ON. But, that costs, and no one wants to pay. Someone bringing his/her vehicle to me is nearly the same as obtaining cabin dimensions for cost and work/time going into the design, so, eh.
