In a recent paper, we proposed a new class of supersymmetric SO(10) models for neutrino masses where the TeV-scale electroweak symmetry is SU(2)(L) x SU(2)(R) x U(1)(B-L), making the associated gauge bosons W-R and Z' accessible at the Large Hadron Collider. We showed that there exists a domain of Yukawa coupling parameters and symmetry breaking patterns which give an excellent fit to all fermion masses including neutrinos. In this sequel, we discuss an alternative Yukawa pattern which also gives a good fermion mass fit, and then study the predictions of both models for the proton lifetime. Consistency with current experimental lower limits on the proton lifetime require the squark masses of the first two generations to be larger than similar to 1.2 TeV. We also discuss how one can have simultaneous breaking of both SU(2)(R) x U(1)(B-L) and standard electroweak symmetries via radiative corrections.
