In the past most solar panels were made in China and had a 25 year warranty. I was under no illusion that even 5 years later that getting a panel replaced for free was remote. Even if free and I have to ship them a panel - Check out what panel shipping costs. There were better quality panels and none of those are on the your list if they even exist.
The RV market for solar panels is very small compared to the home, business and utility markets. Check with solar installers and solar stores and see what you get.
