Jack up both front wheels. Chock rears well and apply just a little power. Watch the fronts. Unless it's one of those rare birds that power the front wheels all the time that case, the opposite works.

With it off in park jack up the front, both wheels. In 2wd and N should spin, in 4 and 4 lo should not.
Make sure you're spinning the driveshaft, and not just the opposite tire backwards through the diff. For that matter I guess you could just jack up one wheel then let the diff handle sending it down the driveshaft to the t-case.
That's so much work though, I'd put the front wheels up against drive on ramps or a curb and the rear tires on dirt. If the rears spin, you're in 2. If you climb over the obstacle, you're in 4.

I don't know what you might see with one of those viscous coupling transfer cases, though.

In Florida there should be a sandy area to try it.
I would just drive down the dirt road to the sand wash and see if I get stuck. Or just jack up the rear axle and see if I can drive off the jack

Go to McDonalds and get a couple of food trays, put them behind the back wheels and back the vehicle onto them, set parking brake, put in 4wd, drive it like you stole it!
