I talked to the factory rep yesterday (8/2/01) about putting the 2.5 inch lift on my 3124 King.    They said the lift kit was about 26 dollars and would take about an hour at $55/hour.     It is not an expensive thing to do.    I have a clearance problem backing down a steep driveway onto a flat parking area and thought that lifting the trailer a couple inches might solve that problem.        Its certainly cheap enough to try it out.
