if you tilt the seats forward there is a plastic tool tray that lifts out and under that is an access cover that also lifts out. easy peasy and then you can see the power steering,the oil cooler and hoses and stuff. you can inspect the stuff above the skid plates and frame for rust,oil leaks radiator hoses and all kinds of stuff. you can see the engine front and timing cover seal and on and on. hope this helps
