Where is my floating ride
 
Just traded my 2013 aspire for a 2014 cornerstone, I was expecting to be impressed with the 600 horse and I am. It's the ride quality that is concerning me know. My test drive happened to be on a freshly laid asphalt road that was about 20 miles each way, however those type of roads are not that common. On my 5 hour drive home this beast rides like a chuck wagon. My hope is I have or am doing something wrong with the Hadley system, every bump in the road translates to a jolt while driving. Needing some advice from all you cornerstone owners.

From what I have found, I'd take a look at your tire pressures. You might have way too much for your loading. If your tag is up where the factory says (like 110) you might discover by getting your RV weighed on each wheel the tire charts might allow you to run 100,95, 90 psi. The other thing is based on 4 corner weighing you might find the tag or front axles are carrying more than they should. A dealer might have aired up your tires to near the maximum labels on the tire. The only way to know is to weigh your coach with your stuff in it.

Yup, get the tire pressures right, then go from there as needed.

Perhaps the air ride is not fully inflated and bottoming out on the frame?

That is what I was thinking. Had a small air leak and the jack retract had to be pushed a couple of times.

:DHopefully Chuck will chime in on this Pun intended )

Check to make sure you are fully aired-up. My drive home was like that and I found the dealer gave me the incorrect start up air up sequence. Once properly aired, it drove nice and smoooth.

Hadley should be set on........STD
RIDE

Get it weighted and I go 4 to 5 psi under suggested on the fronts for the ride quality. Doesn't take long for the pressures to come up when tire temps come up.

That is courting tire failure. Rising pressure when temperatures rise is factored into the inflation tables. That is why the tire pressures should always be adjusted when cold.

Under-inflation is a major cause of blowouts. Over-inflation is safe. For safety, I routinely inflate my tires a few pounds over so they will not be under-inflated if a few pounds leaks out.

So what happens if you use nitrogen .....are they always under-inflated??

That's why I said...."this is what I do":banghead:

OK I will :) It is amazing what an extra 5 or 10 psi of air pressure can make in the ride without being weighed and knowing what the correct air pressure can be.

In a pinch I use truck scale, divide the axle weigh by two, then use the Micheline guide and add 10 PSI. If it rides rough, drop 5 PSI and that is normally almost right on. However weighing 4 corner and watching how you load is still the best method.

I agree on the four corner for sure. My old Cornerstone was #1400 heavy on the right front sending me to Spartan for a ride height adjustment. The King Aire has a great tire monitoring system with pressures and temps which makes it really easy to see what's happening.

the problem with weighing all four corners is finding a place that provides 4 corner weighing. The Cat scales in the Houston area do not.

Many times a local DOT location will have portable scales to 4 corner weigh, or can give a location where the field guys are working. It is normally free and worth a call.
