Yes!  But for two people and 10 days, the larger one is perfect.  If
you sat on both, side-by-side, your knees would suddenly prefer the
larger, since it is taller.  Well, if you have Medicare knees like
me, which I think you do.  ;-)

An option, which I haven't used, is to empty the smaller one in
various BLM or FS pit toilets, every few days as needed.  And
sliding under the bed is worth a lot, when you have a big dog
sleeping on the floor.

Could we drop  the camping talk for a while?  There is a ton of
snow in the high country and it's the middle of ski season and
all this stuff diverts me to think about Moab or Big Bend....
