Thanks for all the kind words, I appreciate it, and I have always felt that this is generally a nice forum.  I'm in very good hands, and if all goes well, I can get back to the trailer before I'm due back at work.  If I can, I'll definitely get the tires looked at and the bearings re-packed (it was due for that anyway).  
I'm sure the trailer will be fine.  You know, for an entry-level unit like a Springdale, I can say that in 5 years of steady camping all summer, it has been a very reliable unit.  The only thing that has been a nuisance is the valve that is plugged into the black tank flush, I've had to replace that.  But I don't use the toilet anyway, so it's not an issue.  I just hope it hasn't leaked.  I doubt it.  I also hope it hasn't sunk into the ground, but the KOA says that doesn't happen there.  And I'm sure a neighboring camper would hook up to my tow hooks if needed.  
Thanks !
Kevin
