Purchased 3 of your 100Ah True Series batteries for my 5th wheel in the spring. I have them hooked up in parallel along with 620W of solar and a 3000W inverter. Camped on and off-grid this summer. Went over a week a couple of times, once with little solar due to tree coverage. Batteries exceeded my expectations. No issues with them at all and they provided all the power we needed. I can even run our RV fridge on electric on travel days which is safer than propane.
