before u condem this guy take a 12 inch level at this spot at the front tire area and raise one end of the level till the bubble centers.then measure how far off the ground the level is.That will give u whats called the pitch.amplifiy that by the distance from the center of the rear tire to middle of front tire. I bet u will find this situation u see pictured here as level and hence why the tires are of the ground as u see.
To clarify what iam saying is take the rear wheel area.Take a string and run it from where center of rear wheel would lay to center of where front wheel would lay.Raise it (string) till level shows level at front wheel center.measure from there to ground and now u will know how much to needed to raise the MH to make level.It can(lot angle) be very deceiving as possible in the case of this one
