2251 Chevy alignment/wandering issue...

So I just bought a 2016 2251 Chevy chassis and after 3 trips (one in the wind) I decided to attempt to alleviate the wandering and tracking issues I have. This is the first motorhome I have driven for any length of time and I seem to have almost constant input into the steering. Road level changes, surface changes and minor cross winds seem to move it around too much for my liking.
I set up an alignment with a local old school alignment guy I know.

I asked him to put in additional caster to help with the centering. He said that he probably could get a degree or more from the factory settings. I have an appt tomorrow and I will post up the results.

Then I should receive a Roadmaster Reflex steering stabilizer I ordered from Camping World. (spring loaded self centering unit). I will also post up after I install that.

Both these items should help with the tracking...I hope.
I am aware of the Ford issues due to the twin I beam config and settling.
Have not heard of any issues with the double A-arm setup on the Chevy.
My alignment guy agreed that all these class C's should be realigned after settling in and will give me a tailored setup.

I think that you'll find that you don't need the stabilizer if the alignment guy does a good job, but it'll be extra insurance.

I received the stabilizer today. No brackets though have to wait at least another week.
Alignment tomorrow.

My history with alignments and my prior vehicles is that the added degree or so of caster helps the most.

I would wager your alignment man will put some caster split of at least 1/4 more caster in the RF to help also.

Did you try adding some air to the rear airbags? My wandered when I first got it but once I put some weight in it and added air to the bags I haven't noticed any wandering.

No air bags. I don't need them.
Rear sits about 2 -3 inches higher than the front.
Spring stack is huge. No rear sag issues.
I did put the front tires up to about 78 lbs- I may try running them a little lower also.

I am aware of that also. Actually- the factories usually put 1/4 more into the right for the road crown.
My does not pull. I will have him put equal "additional" in rt and lt.
Me thinks that will show to be about 1/4 more in the rt.

I have the sameTruck in a 2015. At 5000 miles I added 4 Koni FSD shocks and Safety Plus steering stabilizer. Not perfect but a great improvement, heavy sidewinds are heavy side winds
