I doubt any gas class A has one. I chose Progressive Industries EMS-HW50C with the remote monitor. It has a lifetime warranty. There is a portable version, also. I installed it myself and it has worked flawlessly. Two nights ago at the KOA in West Memphis it shut down power about 6 pm. Low voltage (PE-04) - 92 volts, We had to shut sown everything and check the line voltage - 113 volts. With only the front A/C on, we were able to keep the voltage at 108 volts. At about 9 pm the voltage at the pedestal had risen to 119 so we to run everything normally the rest of the night. So far no current surges or lightening strikes.
