  We study decay and compact support properties of positive and bounded
solutions of $\Delta_{p} u \geq \Lambda(u)$ on the exterior of a compact set of
a complete manifold with rotationally symmetry. In the same setting, we also
give a new characterization of stochastic completeness for the $p$-Laplacian in
terms of a global $W^{1,p}$-regularity of such solutions. One of the tools we
use is a nonlinear version of the Feller property which we investigate on
general Riemannian manifolds and which we establish under integral Ricci
curvature conditions.
