I have had it on my 2005 Lund (and Truck) from day one, and it works just as advertised, and is very easy to install. The owner, Jim Payne, was great to work with and answered all my questions. I’m actually still on my orignal starting battery from ’05 and just replaced the 2 TM batteries last fall. I believe that the Stay-n-charge, has helped extend the battery life. I can use the TM all day and haven’t run out of battery juice yet.
