Wow! I hope I don't ever hit anything like that! Mine is still very touchy to side winds. I am planning on taking it in for a front end alignment before we do any long trips.
Just had to have two trucks brought back from San Antonio that were damaged in the hail storm. Both were brand new when they left NC. I am guestimating the damage in the $5k-$7k range. Had to put windshields in both of them to get them back.
One they were able to remove the dents from the roof of the cab and the doors, still had to replace the hood. The other I don't know about yet.
If you get a chance could you take a picture of the lower rear corner of your large slide while it is in? Mine sticks out a lot further than I think it should, the "middle" corner fits tight, then the gap gets a lot wider at the bottom. It seals, barely.
