Congrats on your new Jeep! I’d second getting the guards for the sills. Otherwise,wait until you’ve driven it and spring. A stock Jeep is pretty darn capable, a Rubi, even more so. For light trails you don’t “need” anything (want is different than need). Drive it, enjoy it and see What you think after you’ve got some miles on it. I Guarantee you will always be able to add stuff later if you wish. The aftermarket for Jeep isn’t going anywhere.
