Instead of a battery in the boot, what about an FLT jackplug under the rear bumper?I was just thinking an occasional Red in a sledge up into my trailer which is the low ivor general purpose type so not to heavy a pull.
Something like a frame with the winch attached dropping over the headboard/ ladder rack and the battery in the back of my truck.
I have my dog box in my truck so don't want a winch in the tub
Take a look at RAC or AA etc jump lead connection on the vans, probably near the bumper?
Make that a proper install with emergency stop mushroom near the back i.e. arms reach and an isolator in the cab. When you need it, slip the trailer flt jackplug into the socket and run it off the vehicle battery with alternator support i.e. engine running.
The trailer carries it's own cables and the truck isn't lugging a spare, possibly already part drained, battery around.
