Our caravan is parked on front of property so give it a glance most days for anything out of place. Yesterday went inside and put all the electrics on but not the water heater and all was well , then gas and that is ok. Went to battery hatch and on opening saw battery spill debris on floor, removed battery and the red lead almost broke in half , just a few strands being connecter to post, as I do not carry that type of large connecter my ones were of normal sizes had to go out . Now repaired for 75p
