Welcome to the forum, and congratulations on your purchase. Since your rig is 11 years old: I'm sure that the prior owner has already worked the kinks out of it. Just keep an eye out for water leaks and rot. (due to age and deterioration)
The best of luck to you with it!

I agree with Paul and Bob. Check the date codes stamped into the tire sidewalls - it’s a 4 digit number that will indicate the week and year of manufacture. Give very serious thought to replacing them if they are more than 5 or 6 years old. Even if they look fine. It’s counterintuitive but important. Also I’d plan on spending an hour or two inspecting every single seam, seal, gasket and penetration on the roof and sidewall. Leaks are serious and water is relentless! Go over the roof on your hands and knees and clean and reseal anything that looks suspect. Use the appropriate self leveling RV lap sealant and definitely not silicone. Use a ladder on the sides and examine every window, light and seam. On the sides use urethane sealant or silicone though the former is preferred. Also check your batteries for age and water level and change the generator oil. Then if everything works just go have fun with your new RV. Welcome to a wonderful forum. You’ll learn lots here and “meet” some exceptionally nice folks.
