Pick up trailer last Wednesday PDI went great. Took it home and loaded it up with all the normal stuff. We drove it over to our storage place and dropped it off and removed the battery and brought it home. Fast forward to today four days later went to go get trailer to bring home. Installed battery and the front power jack would not operate or the inside lights. Checked battery connection and it was ok. Pulled volt meter out and check battery 4v. So i guess my brand new interstate battery that the dealer put in is bad. I just hope that this is not a sign of things to come.
