Hi everyone thanks again for the replies on my post last night. Just thought a few of you may be interested in an update! So, we jump started the MH this morning and got to the ferry terminal (almost) without drama. Driving onto ferry we stalled - look of horror on our faces and also the guys on the ferry as the tide was rising! - jump started again and yay MH + trailer in situ, phew. Arrive in Barra, get onto site, battery still dead as. However, we then disconnected the trailer and low and behold we have no issue with starting the MH!! V battery level on control panel all back to normal. We are now thinking it’s the trailer that drained the battery. We have never had this problem before towing this trailer on our MH. Any thoughts?
