Skamper Pop Up Truck Camper Repair in Los Angeles

Hi Everyone, I have a 1989 Skamper 072S pop up truck camper that I am re-doing. The lift system has torked in the rear corners and I need some help getting this repaired. Can anyone recommend a repair person in Los Angeles who is familiar with Skamper lift systems? Or is there anyone out there who knows Skampers and would like to get paid to repair mine?
Thanks a lot,
Claire
