You have a lot going for you with your rig:
- 99 with low mileage
- E-Locker
- SC'd (Fuel mods? Plugs? Tuning?)
- Skids
- Bumper
- Quality Suspension upgrade
- Wheels and tires
- Good maintenance
- Two-owner vehicle
- Great color!!
- Safe to say it's rust-free??
You won't get the money you want for it in Florida. I don't think the demand for a 4wd w/E-Locker is that high down there. If I were you I would post on CL in the rust belt states, NE, CO, and PNW. This may sound like a ridiculous asking price but I would start at 12,500K and hold out for a buyer.
Just for giggles I checked CL and found this low mileage stock 99 here in Portland OR, with a cracked windshield for $9500.

Good luck and congratulations on your new addition on the way. Thanks for your service.
