I am looking for an owner manual for a 1992 Ford Eldorado that I just purchased. I found an unsecured russian web site with a link but I think it's a scam. Any help would be appreciated
RV maker's owners manuals are usually generic, covering many models, and so pretty close to useless. Similar information, often in better detail, can be found in something like an "RVing for Dummies" book.
Besides the appliance manuals, you probably would want to find/get the Ford owner's manuals for the chassis if you don't have them already.
One thought for the suspect link, take an old cell phone or tablet, reset it to original factory settings, wipe ALL personal info from it, and then, using some public wifi source, open the Russian site. If you get real info great, if not, well they did not get much either.
