I have to say, before we purchased our Liberty, I had my doubts about its rigidity. Now I'm a believer.... This poor truck of mine looks like a giant, four wheeled tube of toothpaste after being wringed out thuroughly in 500 laps with all of NASCARS finest in the sharpie 500 down in bristol.....She's been hit 5 different time the past 4 years. Still runs, still straight n true, No leaks, & just bearly starting to rust.... And I live in Vermont where rust is manditory for open metal.
