I've been browsing the vandwelling sites for a few days now and plan to do this lifestyle when I retire. <br /><br />I got to thinking about heating in vans. Has anyone tried blocking off with thermal drapes/etc just the bed area (and porty potty if next to the bed) and then have the heater placed so it only is heating that smaller area? <br /><br />It seems it would cut down on how much fuel is needed for heating (and yes, I would have the porta potty near the bed, a cold toilet is not fun at night) and you would stay warmer?<br /><br />When you get up in the morning just open the thermal drapes and the heat would escape into the rest of the van.<br /><br />Thoughts?
