Ride Height on Gas MH's

I am trying to determine the distance between the rubber bumper and the upper axle, that is easier to see and measure.

Yes, the "M" value is the loaded height to be accepted at the plant, before it can be shipped, as I was told. As you can see, this is measured at the top of the frame, if I remember correctly.

My thought is if you subtract K valve from M value for your chassis wt this would give you the ride height. Not sure if I am interpreting it correctly.

Can't help but think that we're attemtping to determine the air-speed velocity of an unladen swallow.

What if it's carrying a coconut?

Ford does not give a ride height, because they do not want to be responsible for replacing springs for reasons beyond their control. You will also notice that the springs are a single rate spring, for a soft ride, which can cause early spring sage. Dale's link is straight from the Ford Factory Manual for service.

CLICK HERE for the 06 F53 chassis specs. I've been trying to figure this one out off and on for a while. The problem is I don't know how much the house weights and I'm too lazy to completely unload and then reload weighting all the stuff in the coach. Last page of the PDF has the frame to ground heights and frame to axle heights of the chassis WITHOUT the house. Also included is the leaf spring deflection rates in pounds per inch of deflection.

I'm guessing without be able to actual measure the height before the build out starts I'm not sure what my starting point might be with the added question of how much strength have the leafs lost with time.

Thanks Dale. My thought is if you subtract K valve from M value for your chassis wt this would give you the ride height. Not sure if I am interpreting it correctly.

Unless they are airbag suspension, which will maintain a constant dimension, sprung chassis will vary as a function of load.

Yes but there must be specs that show the min ride height for these MH's. If when fully loaded and there is 1/8 in clearance I imagine it would produce a very rough ride on a rough road once the clearance is gone.

:) 1/8 clearance would be a nightmare.
