Elkmont Weight - too good to be true?

We are prospective Elkmont 22 buyers, and are having a hard time believing the numbers posted about the dry weight. It's obvious what the "pro's" would be to a trailer this light. But what are the "con's"?

And if the advertised dry weight (23K to 28K lb) is not accurate, how can we get a truly accurate weight?

Not that we're generally suspicious by nature but it just has us curious as to why TrailManor seems to be the only company that's discovered this manufacturing process to keep the weight down. Any insights on that?

Bottom line - we would like to tow with a Highlander Hybrid (3500 lb.) and before buying both the trailer and the vehicle want to get the feet-on-the-street scoop! Thanks to anyone who can share.
