So, the Forever Young was launched as a Troll-only in 2008. But as a concept model to celebrate production moving back to Germany. They were then sold, initially, coloured light grey all over for the 2009 Model Year, changing to white over grey from 2010MY. Other models were gradually introduced as the German factory ramped up production. The 2011MY consisted only of one Familia, one Triton and two Troll models, all redesigned to the new FY "shape" . From the 2012MY there were two different Familias, two Tritons and three Troll variants offered. So it looks like no Tritons were produced for the 2010MY. And then only one variant in 2011 - but was that 420 front kitchen, or 430 dinette?

Thanks for much of that info to Steamdrivenandy's blog online:

See, I'd forgotten an awful lot of what I wrote back in 2011ish.

One thing I do recall was that the original year's German built brochure didn't feature a 540 Troll but I seem to recall some were made later in the model year. Could that be the same for a 430?

Certainly the one the OP is interested in is an FYised one with appropriate roofs and washroom.

Easy to tell the difference, the fixed bed models are missing a rear side window.
Mine isn't, we like to change our view point so opted for the 2 rear windows even though it is a fixed bed, much to Camerons horror when we ordered ours 🤣🤣
