NO, do not take that Ranger "off road." I realize that in your particular situation most of the town is "off road," but I strongly suggest you keep it on hardball paving.
Furthermore, I would not suggest putting anything other than air in the bed; thus, no gravel, no animals, etc. Sure, things like "A/C" and a "rear slider" may have affected your judgement, but don't let all that luxury go to your head. It's not intended for landscaping duties. Plus, why would you want to get it all dirty after you've washed it, waxed it, and detailed the bed liner? See, that wouldn't be too good, would it?
Naw, best to just take care of "your" Ranger...'cuz I'd hate to have to report it as stolen.
BTW: You can't "rewind" the odometer by putting it on jackstands and running it in reverse, okay Ferris?
