I leave one back door open, for the reel etc. then shut one over, and lock. I've got a bulkhead, so it Means that if anyone wanted steal anything, poles etc, it would be hard to manouver the poles out there rack.
What van have you got for one door to lock?
I do the same on a Trafic.
I've set the pole rack (guttering
) so that 2 of the 3 poles I carry are hidden behind the closed door, along with the gas bottle & L5.
From a casual glance all a passerby would see is the tank and reel.
But if a scumbag opened the door he'd see what was in there...
