I used Tread Lightly membership to get the no haggle 2% under invoice pricing. You can also try to work from there to get a lower price but none of the dealers around here (tampa) would come down on that. As far as options I definitely recommend the premium top, it seems to be quieter, and maybe slightly better at insulating as well as being nicer material. Also highly recommend side air bags, 9 years in the fire service made this a must have for me. 3.73 rear can't hurt either unless you plan on a major lift and tires later on. Personally I wouldn't bother with the alpine stereo, stock is ok, but the alpine stereo seems like more work to modify in the future. I added a sub and am pretty happy with the regular stereo so far.
Lastly thank you for your service.
