Yes, I put the first dent on Cindy's 85 4Runner a couple years ago taking the hard line at the top of the wagon ruts (sluice).
The only damage I know of other than that was Dalene Hutchings tagged a runner board on her brand new stock runner.
Your only truck worry... scratches from some of the burned trees that are starting to sluff over.
It can be a long ride for young kids. The trail is 14 miles long, and nothing but small rocks making for a rough ride. We have lost wives (that is, they rode once and never again). We are serious when we say light wheeling, but extremely rough and rocky. We leave at 9 AM, stop for lunch around noon, and get off the trail around 3 or 4, then you still have 5 miles of rough forest service road to the campground. Do not under estimate it.
Big tires are not needed. Good 1st trip to hone your skills.
Bring an item to share at the pot luck, and there is always plenty of salads so think main course item or hot item. Dinner is usually about 1 hour after we arrive at camp, so bare that in mind if cooking.
And yes, Rondu and I will provide some deserts.
Big News - This years slogan... Rough and Ready! This is based upon the initial section of trail that we climb to the ridge top is called the Rough and REady drainage!
Oh, and come prepared for cocktails after the kids go to bed.
