Keep your jeep and continue to upgrade. I think you will be money ahead in the long run. I think in the end, you would be upgrading most of the same parts anyway.
Factory lockers are cool to have, but ARBs are a lot better. Rubi tcase, should be very low on the list. You could always look for a front rubi d44 take off for a good price, but probably not the best use of the money.
Buy a good winch and don't go cheap on that. It doesn't have to be the most expensive one, but needs to be reliable. Even if it never gets used.
