Question regarding rear ladder repair

[dandjh1958]

So I got a call from the RV storage place where are poor trailer has to sit when I'm not camping. They told me the neighbor in the north spot parks a large box truck in their spot and somehow hooked up to the chain link fence behind our spots and pulled the fence down. Unfortunately, the chain link rubbed up against the back of our trailer and the only visible damage is to our rear ladder. It has been pulled to the left a little but is still secure on top (caulking seals on the roof are still intact). All bolts are still in and all seals look good on the trailer.
The RV place said the people who pulled down the fence our willing to fix our damage.
My question is- should I take the trailer into the dealer and have them do an estimate? Should I just leave it since we don't use the rear ladder anyway (except to hold the ladder we used to get on the roof). Are there any other things I should be worried about? My main concern is leaking. In Oregon it rains ALL the time!!
Thank you in advance for your wisdom!!
