Looking at "injured" 2001 TM 2619

We have a friend who is selling his 2001 TrailManor 2619 trailer. He said someone had rear-ended it in the past. The accident pushed the tongue of the trailer all the way into his mini-van. He said he sent the trailer to Trailmanor to get it fixed but didn't go into any details on what had to be replaced. (We haven't had a chance to see it yet so we don't know what it looks like.)

We would love to buy it but we have a lot of questions since it was "wrecked". If any of you have any answers we would greatly appreciate it.

ANyone know how TrailManors hold up in accidents? Would a 2001 have a wood or aluminum frame? How about the body, is it aluminum or wood? Would we need to be concerned that the frame was bent? Could there be damage we can't see with a visual inspection? How well could something like that be fixed? Any insight you could give on this would be appreciated. Thanks for your help!
