Sorry this is a bit long, but I am a bit frazzled - please feel free to snip
in your replies and thanks for them.

Well, my Coleman pop-up got rear-ended while I was waiting to make a left
turn today (I was stationary with the turn signal on).  While I am not
pleased at all about this, no one was hurt and I just need to pick it up
from here and understand what I need to do.  Advice from anyone is
appreciated.

So the guy in a Quest hits me fairly hard, with the center of his vehicle
lined up with right side frame member (his license place was stuck there
when we disconnected).  The back bumper is pretty much mangled and a lot of
the plastic (sheet metal equivalent? - what do you call that stuff?) is
cracked but my real concern for the trailer itself is that he bent the crank
receptacle.  If it now pointing off to the side somewhat.

The other big concern is that it pushed my trailer hitch up into the bumper
so that I cannot now even disconnect the vehicles.  It towed home OK (done
carefully and it swiveled OK and all).  The ball itself is now pointed maybe
30 degrees forward.  Using the lift crank just never really moved off at all
anyway, but if it did it would have wedged it into the bumper moreso.  The
arm that fits into the hitch receptacle and holds the ball (sorry for not
knowing the right words...) has not been removed in ages and is in there
solid - I thought the easy way out would be to remove the pin and let it
slide out, but it is in there good - likely a combination of being rusted in
and not being able to pull it out in a straight line (probably moreso the
rust) (when I needed to change ball size I just changed the ball itself).

Now I have questions:
Insurance: I am assuming (hoping) that the other guy's insurance will pay
for the camper repair too.  When I called it in to the week-end insurance
phone form filler-outer she asked me if I had the trailer insured.  I do not
specifically - I am thinking that I had asked this at one point and was told
that the car is insured and anything connected to it (like the trailer).
Does anyone have any experience with this that they can enlighten me a bit?
Thanks.

Repair: Who do I go to in order to fix this manner of damage?  I am betting
that it is a different place than the car, but I am finding myself a bit
clueless on this one for the pop-up.

Disconnecting it from the car: Cannot remove the ball holder thingy.  Cannot
remove ball.  Cannot lift off.  I am thinking cutting through the thingy or
maybe the auto repair place can do it. Thoughts?

What else should my jumbled mind be thinking about regarding this?
Thanks very much to anyone who responds,
Tomes
