It does look a little like a T@B, because (like a T@B ) it has the classic "canned ham" body shape (imagine an actual canned ham, on its side...) composed of flat sides and bent-panel front/top/back, but with a squared-off tail. I think this makes a lot more sense than the full teardrop treatment. It looks best to me in the little 310 model. Of course, the panels of the T@B are assembled to each other and the framing with fasteners and trim, not bonded together like this one.
As usual for European designs, the
axle is very nearly centred in the body (rather than significantly behind the centre like our Bolers
et al) to produce their preferred low tongue weight.
In case anyone didn't notice, there is a link at the top of the page labelled "Click for watching the advertorial" which provides a 12-minute streaming video movie which shows off the construction details of this model series quite well (then also shows their larger trailers and portable/modular structures), although I'm still not sure exactly what the suspension is.
As Joe noted, the construction is interesting: the trailer has a welded metal (presumably aluminum) structure and the body panels are bonded to each other with more glass and resin, as described. Is this really "moulded"? The end result is painted (or gelcoated by spraying, not in a mould). The other detail I noticed in the video is a slick table folding mechanism.
I'm sure Charlie's conversion calculations are right - they certainly look reasonable. I use real units of measure (the ones used for most serious work - metric), but often to convert to pounds and inches for this forum, because that's what people seem to be expecting. I have taken the liberty of copying his table here and adding the 310 model:
Item..........310..........450..........570

The 310 has sort of a reverse-direction version of the classic
Trillium or
Boler 1300 layout, but still squeezes in the bathroom without giving up either seating/sleeping area (they use a fixed bed and two-person dinette) - that's one packed unit!
If this one is considered strange looking, then Airstreams latest oddity (the
Basecamp) must be as well.
