I purchased new batteries for my airstream interstate. The batteries worked for 1 day. At there behest, I took my motor home to RV one in Des Moines. At first they didn't know what was wrong with my rv, but then they figured out that the batteries are not holding a charge. I took the batteries back to camping world Cedar Falls. They promised me a refund and took the batteries back. They never gave me my $900+ dollars back and they kept my batteries.
