Battery isolator for trailer wiring

Hey all-

   I have a second question about my new truck, but I figured I'd start
a new thread so the two topics don't get mixed. My '05 has the factory
tow package (which is way easier than having to do the wiring by hand
like on my previous truck!). However, it says in the papers that the
package does not include a battery isolator. In other words, if I stop
the truck and don't turn off the fridge in my camper (or unplug the
trailer) I'm going to run my battery dead in short order.

   On my last truck I put a relay on the charge wire and had it switched
by tapping into an unused switched fused slot with an "add-a-circuit".
It worked just fine, but I figured since I got the tow package there
might be a simpler solution (or at least not a hack like before). I
haven't really dug around and figured out the wiring (too cold and no
room in the garage). Does anyone have any experience off hand?

Thanks,
Korey
