Jumper wires aren't always hot and the trailer plug is pretty low current. Anyone truly considering this with isolation should be running a power wire to one of the batteries (fused, obviously) and just using the chassis ground.Now that I think about this a bit more... The "jump" point connections behind the rear bumper, are those 2 points hot all the time, or only during a jump? If they are hot all the time, it just got a LOT easier. Install a battery isolator with those 2 wires, find a 12v reference for the switched side, and connect your battery.
Could even use a set of those quick disconnect battery jumper plugs to make it easy for removal of your remote battery.

Edit: The only caveat I can think of, is you dont want to have 2 dissimilar batteries. So you may have to buy a replacement battery for under the hood, and your remote, or buy a factory battery for your remote.
Edit2: Or what about the 7 pin trailer plug. It sounds like it might already have a isolator in it?
