I have a decent amount of boondocking experience. But it is not setup as nicely as Junkers12. Our first trip with our HTT, was for three day weekend at a SP, with no hookups. At the time we still had incandescent lights in the unit a single group 24 dual purpose battery (still have that battery). I talked a little about power consumption with the DW and kid, but did not push the issue. I let them use as much DC power as they wanted. About mid morning on day two the battery was done for. I plugged the TV in and ran that truck for about 30 minutes and got a decent charge. That evening the same thing happened, battery was weak again. Plugged in the TV and ran it for about an hour (it was raining and I was in no hurry to go out and unplug it). That final charge got us through the rest of the weekend. When we had run low on power, the wife and kid started turning off lights, started listening to me about only running the light s that are needed and to only turn on one of the two lights in the ceiling fixtures, as they where worried about not having enough power for the pump or the refrigerator. Now with a little learning and LED lights, we can go out on three day weekends using some heat and only needing the one small battery with no external charges. If I do not need heat, we have been out for 5 days on that single group 24 battery. If we are out for any amount of time without any hookups, I carry a second group 27 battery in the back of the TV that I can switch over to as needed. Done it, but rarely ever need to.
It is also very surprising how fast you use water. For example when off the grid, to wash our hands we turn on the water long enough to get them wet, to turn it off, soap up, turn the water on long enough to rinse. Dishes are done about the same way, with four of us we can go for about 4-5 days on a single fill of our 29 gallon FW tank (no showers in the unit).
With Junkers12 setup and a little learning he should be fine, until he wants the AC or microwave. The key for me is the learning curve not just in electrical use but with water usage.
