Yes I do. The way my RV is set up it was easy. The battery is under the step, all I have to do is open step hook solar to battery and I set it in the side window which faces south. The unit I am using was bought at Bass Pro and it is only 5W but if the battery is fully charged it keeps it up even with below freezing weather. Now with that said I did replace the Harris junk battery with an Interstate.
