I understand your hesitation, it's like when you get a new cell phone or something similar, you're careful to set it down so it doesn't get damaged but once you get that first scratch on it you quit caring as much. I'm sure the first time you decide to take the Jeep off the paved road onto the fun stuff you'll realize how much fun it is and why there are forums like this one. You'll probably end up keeping it a lot longer and it'll turn into a project like they do for most of us on here. Also as far as frame sliders go you can find some that will bolt onto your chasis which don't require any drilling. Happy trails.
