No, both axles scrub evenly. Unless you have torsion axles and don’t have the trailer setup level. And they don’t stay on the trailer long enough to go bad, they should be replaced every 5 years.
So balance is all that is needed.
This.
The trailer rotates about the center between the axles. But really most RVs spend 99% of their miles going down the road where there is negligible scrubbing. Far less wear than a car in city driving.
As mentioned, you almost always age out a set of tires long before they wear out...so there is no harm in rotating them but I wouldn't spend money on it.
