Smoother Ride

Hi Everyone,

I currently have a Majestic 19G. It has the Ford E350 and rides like a truck. I am looking to make the ride a little smoother.
Any suggestions on how to make that happen?

R,
Chris

The 19G has single rear wheels, correct?

I know of a few things you can do.

1) Weigh your rig during a trip at a truck stop. Weigh it with a full tank of gas, water, people, gear, food, everything. Weigh each axle independently. With the weight numbers, you can then adjust your tire pressure to the actual load on it. You might be adding extra air creating a rougher ride than need be.

2) Replace your shock absorbers with Koni-FSD shocks. Beware that they are quite expensive.

3) Back to the weight of each axle. If your front axle is very light weight, you might have excessive front coil spring load margin. CLICK HERE to read my experience with changing front coil springs to one rating lower to soften our ride and level our rig.

Tireman9 is a retired tire construction engineer, he says to add a minumum of 10% of air pressure over the chart listings.
When you have a truck chassis it WILL ride like a truck. The cheapest solution is to drive slower.

Exactly. What Ray said.

As noted, it is a light truck chassis. Trucks do not ride like a Caddy. Yo can see if Kelderman makes an air ride suspension that will work on that chassis. If they do, it is not cheap.

We changed to Bilstein shocks and it helped.

I wonder if this recommendation comes in-part from tire gauges varying so much.

Over the years, I collected quite a variety of tire gauges. I performed a comparison test on them to learn that they varied by as much as 20%. CLICK HERE to read about and see my evaluation.

Ron ... thanks for you great post comparing tire air pressure gauges!!

How do you use the Accutire gauges on the inner rear dual tires if you don't have extensions on the those tire valve stems?

I find that the truckers type mechanical gauges reach the inner dual tire stock valve stems pretty well, so that's what I use. (I don't trust valve stem extensions because they introduce more potential leak points wherever they screw together.)

You are very welcome!

My rig always had valve extensions for the rear dualies.

Before with steel wheels and wheel covers.


Currently with Alcoa alloy wheels.

Yes, but those who are telling you to overpressure the tire are just being safe or as Ron says may be making up for the wide variation in accuracy of tire pressure gauges. I can tell you from experience that a tire will perform better if it is pressured per the manufactures load and PSI tables. Yes you can get better fuel mileage by running high pressure in your tires because it reduces drag but it will make the tire wear in the middle, have a harsh ride, and the steering will feel light on the front. When a tire is pressured for the weight the footprint will be optimum. Everyone should know at a minimum the weight on each axle of their RV and if possible get the weight of each tire position. This service is sometimes available at rallies. Folks should also know that tires have a speed rating and sustained operation at or above that rating can lead to tire failure. Believe it or not many tires for trailers and RV's are only rated at 65 MPH.

if you havenít had an alignment done on the unit, do that first. I did mine at a truck shop and it drives like a car now.
