Yay! Congrats!
Now the long wait starts! but you can fill it with lists of things you need for it, cruising Amazon for said items, receiving said items enough that you get to know your UPS driver by name (not that I know anything about that!), plotting where you'll go in it, where stuff will fit inside, etc, etc.
And changing your info on the left to what you now have on order!
And most of all, working on that build sheet and reading as many posts here as you can to get that sheet completed. Have fun! I know I did.
