Recent issues off the top of my head that I've had with recovery of these trucks in the last 3 months:
1. ABS light stays on - means 45 max safe speed until repaired
2. Rear brakes locked - if they rolled freely in the GL video, you're probably OK
3. Missing parts - throttle linkage nut, turn signal switch
4. Dead batteries
5. Fan clutch not working - starts overheating when idling
6. Tires flat
7. With no cover, the center stave of the rear bow fell out onto the road after about 20 miles
8. Bobble head axle vents plugged, pushing differential gear oil past the axle seals and slinging oil everywhere
9. All the nuts on one rear axle end cap were loose and gear oil flowed like water
10. Soft top seam came apart during a rainy day - gorrilla tape worked well
11. Gauges like transmission temperature, fuel, oil pressure and speedometer did not work or did work but were inaccurate
12. Bad ground cable for the batteries - wouldn't allow a jump start
I hope you have better luck, but plan for the worst. Most people have recoveries that go well, but there are some disaster recovery storys where Murphy joins the ride. Take a LOT of cash in case you need a tow off the highway - many tow companies will only tow if you have cash to pay.
