I am having a custom trailer built and wondering what some of your ideas have been or would do if you could build your own trailer. Some of mine include, running a 7' ceiling with a drop ceiling and running heater ducting through ceiling and down walls. Walls will be 3-4 between outer skin and inside wall to run ducting. Also would like to try and rig up in floor heating like they have in houses. These are a couple ideas, would like to hear of things you wish your trailer had so when I build mine I can have it all decked out. thanx
