Bet you're excited!
Couple things I would consider doing first (other than changing out all the fluids so they are fresh - Engine Oil, Trans, Coolant, Transfer case, Diff's, Brake, & Power steering):
1. Grease the pop-top tracks and the silver posts attached to the crossbars
2. While the top is up; clean the canvas & the windows (inside & out), and apply a protectant

***You can use the same on your Awning
***I would also apply a zipper wax to the pop-top window zippers so they slide freely
***WATCH the pop-top hooks when you raise the top, they have been known to 'catch' the latch and if you're not careful you will/can bend the cross bars. Couple Threads sharing ideas how to guard against this.
3. After a good cleaning, you can bring the Aluminess stuff back to life with Woody Wax (also good on Bushwackers, Tow mirrors, running boards, etc) - I apply it about 3 times a year.

***If you have scratches on the Aluminess you can use the same spray paint they use to cover up (If your Aluminess is heavily faded you may have to paint the whole thing, but I would try buff it back to life first):

4. I would sanitize the water system. I personally don't use the water system in the van for drinking water (carry a 3.8 gallon Waterport and a couple Scepter runts on the top of the Aluminess box at the back of the van - they fit perfectly)

5. If you Have a CO2/smoke detector installed - look at the date (they recommend replacement every 5 years - should be a date printed on the front of it). Would also look at the Fire extinguisher.
One of the best upgrades for the Van is installing new Headlights that actually shine some light down the road - I'd recommend Vantage Optics (Scott is also a member here). His units make a huge difference.

This should get you started...Follow along with the Threads that pop up - Lot of useful info, but you'll also get sucked into all the enticing upgrades/additions members share that you'll want too!
Congrats on your new toy.
