Please forgive me for another post about steering 'wander'. We have a new 2017 Winnebago class A that has the dreaded wandering problem (don't they all...maybe except the very high end units).

Don’t forget that there are factors over which you have little if any control.
First and foremost, unlike a car, you are talking about a vehicle that has a sidewall area of probably 10’ x 30+’ or about 300 sq. feet. Adding to this problem is the chassis itself, in a DP the axles are basically at each end. In a gasser the rear axle is almost amidships. The leverage of a crosswind (natural or the ‘bow wave’ of a passing truck) on the rear ‘overhang’ means the coach wants to swivel on the rear axle.
Lowering the tire pressure to match the inflation tables instead of running the pressure on the placard in the drivers door jamb (or elsewhere) means the tires are more prone to sidewall flex. The sidewall flex adds considerably to the overall problem.
