Reading and responding to the threads about Propane and Toads got me to thinking. I was looking at a wide assortment of RV's in different configurations, and their primary restrictions when it comes to boondocking all seem to be universal: Water / Power / Food.

So, as I was looking at a 24 ft. Leisure Travel Mercedes with a small 3 liter diesel engine, I noticed that it was still capable of towing up to 5,000 pounds. Looking further at some of the Class A diesel pushers, I was surprised to see that some of the larger ones can pull up to 15,000 pounds. At any rate, just about every make and type of RV either comes with a trailer hitch, or is capable of supporting one. 

But back to that Class B, I was thinking that you could tow quite a bit of stuff at that particular limit, even with the weight of the cargo trailer subtracted. Now I'll be using some extremes here for each of these individual resources, just to give myself a rough idea as to what is possible with each: For example, a plastic, 300 gallon water tank, filled to capacity weighs roughly 2,700 pounds. A pair of 120 gallon LPG tanks is roughly 1,300 pounds. I haven't done much research on Solar, but from what I've seen a 480 watt array with half a dozen deep cycle batteries doesn't appear to weigh much more than 1,000 pounds. 

Now .... if you had a small, twin axle cargo container, properly outfitted, say something around 12' x 7', and covered with solar panels, you could put together one heck of an "Energy Pod" or "Sustainability Stash" if you would. Throw in a composting toilet, and a wood burning stove, and you could stay lost for a pretty long time. 

Of course, I'm just throwing stuff up against the wall here, but that's half the fun of dreaming about all this stuff.
