Welcome...
1. Don't let the issues popping up here seem as if it's a widespread issue as others have stated..
2. I ordered my truck from the factory (5 month wait) without a moonroof because of possible off-road/leaking issues..that being said it doesn't mean that a high percentage of those WILL have issues..
3. Most important!...Don't overdrive your truck!...my last truck (2004 Nissan Titan 2wd set up prerunner style) had thousands of off road miles, and hundreds down in Mexico and never had a serious issue out playing in the dirt. I always drove the truck at no more then about 75-80 percent of what it was capable of so that if I ran up on something (whoop, dip, road crossing, etc) faster then I should, I have a little more truck left to handle it.
If the road or course was getting nastier, then I'd back down a little...remember it's not a Trophy Truck...but I do consider it a light prerunner when driven smartly..Several times I've had to say to myself "Remember Louis you have to drive this home"....
