Ride Height on Gas MH's

I have been looking at gas MH's 2006 and newer and have noticed a lot of variance in the ride heights between MH's and from side to side on the same MH's from the rubber bumper and upper spring set on the front ends, mostly on the Fords. Does anyone know what this dimension should be for both the Ford and Workhorse? Workhorse seems less than the Ford from what I have observed.

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.

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.

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.
4 whopping cylinders on Toyota RV's. Talk about great getting good MPG. Also I have a very light foot on the pedal. I followed some MPG advice on Livingpress.com and I now get 22 MPG! Not bad for a home on wheels.

Both Ford and Workhorse offer several chassis models and each has different ride hight specs respective to that model.
Side to side there should be no difference on either, something is wrong.
