Can you really boondock in the Summer?

Our biggest problem for 6+ days is gray tank space, not power.

In my case, my buddy gave me a key to the church and they had a shower in it. At the end of the week, my gray tank was only 20% full and only because I did a load of laundry. But under any other circumstance, I think you are correct. The tanks would fill faster than I could burn the fuel.

From all the responses I've seen so far, it looks like summer boondocking is not going to be a very economical endeavor. Worth it for other reasons perhaps, but not simply to save money.
