I have had new batteries all along including the one in the truck now which is only about 3 weeks old and every time the truck sits for too long without being started it will go dead.The drain has ruined 2 batteries,replaced under warranty thankfully.I measured the draw at 1.5 amps engine off and I'm not sure if that's common or not.I don't have any aftermarket stereo/amp draw,the truck is stock other than the remote start.The connections are so fucking clean from being taken on and off it isn't funny and yes they are tight.If anyone takes the time to read my original post you'll see that as long as the r-s module doesn't have any power going to it (fuses pulled) the battery will stay up.
Any more thoughts?
