I finally got around to modifications that are well documented on this site, the tent in the vent, oxygenics shower, digital thermostat and the screen door opener. All went well and work great. Thanks to all of you for your ideas. Heading out west for 5 weeks so these mods will come in handy. Also finally got rid of that awful rock hard matress that comes with the Bighorn, found a king size air matress with builtin pump by intex that is the exact size and topped it with 4 inch foam. A lot less weight and much more comfy.
