Trojan T 125s 2 6 volt GC batteries. Sold my first TT with them on after 10 years going strong. Bought our second TT now 5 years, selling that. Upgraded to a Fifth Wheel, added two more for 4-T125's As mentioned never let them go below 50% and they will last forever.
Present set up, as we dry camp a lot. 428 watts solar, 4 t125s, 2000 watt Xantrax inverter. Led lights through out. Turned off converter, frig and water heater to gas, plugged in inverter and fiver is powered up. Adding a few more solar panels. Only issues are long dark days. We also carry a honda 2000 for back up. Hope this helps.
