Well.. If I'm going to drive the 8mpg RV instead of teh 25MPG Car I got to have a reason.. Fun works.
Example.. If I am taking a bunch of kids sledding,, The RV kitchen makes great Hot Chocolate
If I get to the parade route early I have a really nice elevated DECK to watch from.
And that is just two examples of cases where it can be FUN to drive the house to the event instead of a cramped car.
Have yet to do those with this class A (Kids sledding.. Kid is 33 about to become a mother). but... Back when I had a van (Semi converted) I did use it in the manner specified here.. Very nice to do,, Most of the comforts of home.
