As I recall, your Airstream is missing some interior components. How about estimating how much weight, and add that back inside in the form of concrete blocks (33 lb/block). Then add blocks in the form of gear/food you might have in a typical trip, and have another look.
Hopefully, your axles will still look okay, but you never know.
The photo is befor I removed the sleeper sofa and kitchen, which was made of 2x4 and 3/4" plywood. Also, the matress and abunch of other way heavy items. The traier is sitting higher now.
