I have been leaving the TV in there when traveling. So far, no problems with rain or outside elements. On the compartment to the right of tv, that's is where is the A/C and cable, this is where I also installed the XBOX 360. So you have to drill holes in the compartment linings to make the wire run. I used two 1" holes, if you want a real clean install do a 2" PVC pipe in between and caulk real good. The part that takes the most work is running 12 volt wires to the batteries below the steps. This is what I used to power the 12 volt stereo, this is nice because you can runthis without having AC hooked up, nice for a short stop or camp trip. We're actually on vaca at Mt Rushmore and we have the entire rig up at Horse Thief campground, everything is working great! We get allot of walk by's and good comments on the stereo and TV. Remember to get those kids away from there and be outside playing, walking and enjoying the nature!!
