Tire Feathering after alignment

My 2004 Winnebago Ford E350 has Michelin tires that were put on last January because of the recall. 2 months ago, I had it aligned for our fall trip to Arizona. Tires had no wear. We traveled about 1400 miles and most of it was fighting high gusty winds. Usually had the wheel at 11 o'clock or 1 o'clock for hours at a time. When calm, the MH tracked perfect. When we got home Saturday, I noticed that the tires had feathering not just on the outer edge, but across the entire tire.
Checking the web, I found that feather is usually due to toe in. Could the feathering be caused by the wind? I have the computerized alignment numbers before and after going back 6 alignments and the toe in is well within the perimeters set by the manufacturer and the after alignment numbers.
The front tires will probably have to be rotated either swapping sides or swapping sides with inner duals because of stems. Alignment shop only guarantees alignment for 30 days and it's 65 days. So I would probably have to pay for another alignment, or perhaps they may give me a break on price.
I think it's the wind! What do you think?
Oh, the tires were properly inflated for my weight and I checked them daily while on our trip.

  • Incorrect toe in feathering pattern should appear to be "opposite" on the other tire ...I think... if that makes sense...

    Feather from hours of left or right rudder input to trim for crosswind should appear the same on both tires... I think... the one near side to the wind less than the opposite side because it was running more in line with the vehicle direction, the off side was running with "more toe in"..

    Your MH has needed 6 alignments in it's life? What were the causes of the un-alignment each time?

    We live in a windy place so alignments are kind of useful about 20% of the time :) And our tires get scuffed off the other way because the wind generally manages to swing round so you are headed crossways into it on the way home too. :)

    Just some ideas
  • Can you take a pic? The direction of a feathering is a good way to tell what is going on.
