Great trip report. Do you by any chance have photos of the above passenger door grab handle and details of how you mounted it? My wife, too, would like such a thing.
I'm traveling on business now and don't have a picture of it. I'll try to remember to take one when I get back and post it.
I pulled a sampling of handles from various wrecks at the Pick&Pull. I don't recall what vehicle the one I used came from. I drilled into some structural steal in the area above the passenger window, installed a couple nutserts and just screwed it in. My wife used it quite a bit on that trip while 4wheeling and it didn't pull out, so all's good!
