I've run meshes with several million elements on my desktop with several non-linear variables per DOF without memory issues. The mesh data structure is relatively small compared to your equation systems (unless you are running really simple "single" physics problems). If it fits in memory, you'll also get the added benefit of speed over using parallel mesh since you don't need to do as much communication. When we go to the cluster we still don't use Parallel Mesh since it generally costs you in terms of time. Just a few thoughts for you to consider before you spend more time working your ParallelMesh issue.
