Wherever the trailer you're considering might be, there should be a nearby truck stop, moving company, or whatever that has a CAT scale. These can weigh a big truck (movers charge by the pound, truckers deal with load regulations). Easy enough to weigh an Airstream there, assuming that the trailer is in a towable condition.
Airstream owners use these scales to adjust their tow hitch settings. You can deal with that once you've chosen your trailer.
