Looks good! Welcome to the blessing/calamity that is aluminitis.
It being springtime, you might want to get all the systems running, repack the bearings, adjust the brakes and go camping!
Lots of folks get all caught up in restoration and modification before they have ever spent a night in their new (to them) trailer. I recommend you spend the whole summer having as much fun in it as possible and the decide what changes you would like to make.
We have a 31' so we understand long trailers. It really isn't that big a deal. Grab up some empty cardboard boxes to use as obstacles and find yourself an empty parking lot to practice maneuvering. You will pick it up really fast. The long trailers are really stable and tow wonderfully.
Go forth and enjo,y the journey,
