Will pulling a 05 sedona sideways out of the mud damage the van?

A friend got the front wheels of my 05 sedona stuck when they started to
go through my side yard which created very deep holes.

The tires were stuck so deep the towing service said they'd have to get the
van out of the holes to get enough traction to pull it out completely.

To do this they said they'd have to pull it from the side.  They attached the
wench underneath the back sliding door on the drivers side, pulled it part of
the way out before hooking it up in the front to pull it all the way.

I don't know what they hooked it to on the side, but does anyone know if
this could damage the van and if so what symptoms would I look for?  

Thank you...Suzanne
