Serious case of camping desire

There was a time when the Phactors were big time campers, but then life got in the way.  Now with retirement looming the time is coming when we may be able to resume our camping, but our bones are no longer so well padded.  In other words while we like the great out doors, a bit of padding between the ground and our aging bodies is a great idea.  Now this is one neat little tent trailer and basically we want it!  Badly!  How cool is this?  Go look at the various options.  Oh, yes, this is one nice little outfit.  But where is the solar power?  And why is it named after an insect?
