That is not what is the normal definition of oversteer and wound more commonly called plain old loose steering and wander. It would commonly be worn parts in steering linkage, maybe a steering gear also, outside chance loose wheel bearings. Correcting the wheel track front to rear with spacers can also help as does making sure the shocks are good and often upgraded.
The affect can be magnified by a vehicle that understeers, and nearly all class b RVs have underesteer, some more some less. The Fords are generally on the less end of the scale. Understeer makes the steering inputs not turn the vehicle enough to correct normal movements of the vehicle side to side from wind or uneven pavement. This means larger steering inputs than would be needed in a fast reacting car like a BMW, for instance. If it is not tolerable is a very subjective thing with some, like me, not liking it at all and some tolerant of a inch of correction in wheel being needed, or more. For reference, if you look up the definition of understeer it will state more rear traction than front and would be shown in the front wheels skidding first on hard cornering or on a skid pad test. Basically, whether you go of the road because the vehicle didn't turn. In oversteer the rear would have less traction and slide first, so you would spin out.
If everything in the wear item and track are made good and it is still uncomfortable to drive, then a large rear swaybar would probably be the next step as that will generally reduce understeer a lot.
