I have an XP and I mounted it on the bottom of the muffler. It was about 25 degrees out when we were on our trail ride. I thawed the burritos before we left. It warmed them up, they were warm all the way through. It would work better if you could mount it somewhere underneath the bed. It would get a lot more heat under there. All in all it worked. I will have to try it with beanie weenies to do the true test.
