An ambulance company hit our Camper

It’s a sad day! An ambulance had backed into our driveway and hit our stored truck camper resulting it to fall off of the stilts and crash to the ground. The structural integrity is in question now that it fell forward and to the side placing all the weight onto the over cab bed corner :(

What’s most unfortunate is that it’s older so we’re worried we won’t be able have their insurance pay for a camper of same quality.

Does anyone have insight on how to get the best possible outcome with someone else’s insurance? We’re not looking for much, just enough that will get us back to where we were at. Thank you!
