Had mine delivered yesterday. Everything went well except the auto connect deck demonstration. Sending someone out in the next week try and get it working right for me. Would not click into place. And yes as I had suspicion beforehand... the deck wants to slide on the concrete floor.Although I got my 1026r last October, now is the first time for me to use the AutoConnect deck. It seems to connect very well on asphalt----but in my garage that has sealed concrete floors it is very tempermental. Does the slipperiness(is that a word?) of the sealed floor make the difference. Are any of you out there with sealed concrete floors having problems?
