Checked a few dealers here in San Antonio, and it doesn't look like they're even talking percentage below MSRP or invoice. Just $500 to $1000 discounts.
Since the 80s, I've had a CJ-7 and two Toyota 77 FJ-40s that I went wheeling with. I never used anything but a Hi-Lift jack to swap in a spare tire or work on brakes, etc (with the addition of jack stands). You just got to use common sense!
