hook up a box in your truck that sealed, run a sine sweep or through the system. have your mic reading with the rta. this will show you peaks in your system, whichever note is highest on the spectrum analyzer. your resonant freq. is a termlab comes with its own dta program.

yup, it does vary.
you can measure the sympathetic frequency of the cabin using an RTA and signal generator.
most high end car audio shops can do this for you.

sound deadening the entire car interior is a good step toward lowering the Fs of the cabin, for what it's worth.
