We construct an SU(2)(L) x SU(2)(R) x U(l)(B-L) model with a Higgs sector that consists of a bidoublet and a doublet, and with a right-handed neutrino sector that includes one Dirac fermion and one Majorana fermion. This model explains the Run 1 CMS and ATLAS excess events in the e(+)e(-) jj, jj, Wh(0) and WZ channels in terms of a W' boson of mass near 1.9 TeV and of coupling gR in the 0.4-0.5 range, with the lower half preferred by limits on t (b) over bar resonances and Run 2 results. The production cross section of this W' boson at the 13 TeV LHC is in the 700-900 fb range, allowing sensitivity in more than 17 final states. We determine that the Z' boson has a mass in the 3.4-4.5 TeV range and several decay channels that can be probed in Run 2 of the LHC, including cascade decays via heavy Higgs bosons.
