If you’re starting off from scratch I would have to say tires. You can get to plenty of places without a lift, or skid plates, but street tires may not cut it. If you need or want to do a lift I would do the lift, then go for tires. After that it’s whatever you want or feel like. Navigation, Communications, etc. ect.. We will be more than happy to help you spend your money. Just have fun with it.
