Real-Lite 18 foot camper trailer info needed

Hi. I might not be in the right forum, i have a 1983 Real-Lite trailer camper by Juno Industries. This trailer seems to be extremely rare as there's no info on it anywhere on the web. As such, I wanted to reach out here to see if anyone could share anything, particularly looking for original equipment details like what kind of refer/water heater/furnace was used, what sort of control panels if any were originally installed. Specifications and owner manual would be super to have. I'd like to put the trailer to the original shape as it's missing practically all of it's original appliances.
Thank you.
