You may want to check with your local golf car dealers to see if they are a Trojan dealer. The Trojan site will show the dealers in your area.
Current price at my golf cart dealer in Charlotte for the T105s is $124 + tax and exchange. Last time I bought 2 of them there, they threw in a removable Trojan lifting strap. You really need that to deal with them.
I got these about a year ago. I have the Iota DLS-55 Power Converter/Battery Charger. I immediately added the plug-in Iota IQ4 Automatic Charge Controller as I leave the RV plugged in most of the time. Even so, when I checked the water last fall it was way down and took a lot of distilled water.
