Battalion 31

I recently purchased a 2018 25bh travel trailer
When we were doing the demo at the dealer, the inline fuse for the exterior battery blue and was replaced by the tech, We've had the unit out twice since and the fuse has blown each time, Before I left home I replaced the battery with a newly fully charged battery and after a 2 hr drive sure enough the fuse had blown again. Positive cable connected to positive post on battery and negative to the negative post. I'm at a loss ( nothing wrong with the batteries) What would cause the inline fuse to the battery to blow other than something causing the battery to heat up???

Are you sure the fuse didn't blow when running the tongue jack up or down? That happened to many of us.

He may have installed a regular type fuse, you need a slo-blow fuse.
