Hi and welcome .
No matter what you do to restore your Compac Camper take photos before during and after the work . These will be of great value when your memory is in question about how anything is reassembled.
The front cover fiberglass panels can be removed and reversed in the frame if badly weathered. I did this with mine and after using a skim of car body filler painted the inside to match with RV white in a spray can. I could not find any panels anywhere to replace my originals .
I noticed the plastic trim strips are missing on your trailer .
The aluminum trim had a plastic strip inserted in the center (white or black most common ) Truck box caps and Rv's use this strip so you may find some where these caps are sold
You will want to replace all propane
fuel lines for safety due their age ! Unless you can confirm this has been done already ask a repair shop for help if you aren't sure about them . You may have to visit scrap yards for some usable items that are no longer available to replace items.
Good luck with your new trailer and I wish you many happy times with it ! Duane
