I spent several hours running the BillyBob SUV through its paces on Palmer Park's green and blue trails.
Box-O-Rox was eventually loaded with about 50 lbs of rock; but BillyBob still easily handled the blue (intermediate) trails. In fact, the heavier Box-O-Rox got, the more stable BillyBob became.
Test-Run: SUCCESSFUL!
Coming up... BillyBob Goes Fishin'!
