Welcome to the clan! And, congrats on the "new" Funlite. It looks like you covered the bases pretty well. If you haven't already, get up on the roof and check it all over for any cracks or holes in the seams and caulking or where any openings are for vents, etc. The last thing you want is for your new toy to have leaks anywhere. Water can do a real number on a trailer. You may want to do a new caulking job and a roof coating, it is cheap insurance.
When you are done with the roof crawl underneath and check the lift system. Check the cables and pulleys for wear or damage, check the hydraulic cylinder to make sure it is okay, and clean and lube the guide rod that parallels the cylinder, that is a very important item to have in good working condition to prevent damage to the cylinder. While your there check the safety catch to make sure it isn't bent or damaged.
After you get all rested up go and enjoy your Funlite!
