My Trigano Silver 420 CP

I have the 420CP with a fixed double bed at the front.
This page from a Dutch site, shows the models as they were in 2007.

This page shows the 2011 configurations.

They all

• fit through most standard garage doors (so can be stored in garage if sufficient length available)
• have solid sides
• have good storage
• are lighter to pull than similar fullsize caravans
• are said to be more stable for towing (apparently 1/3 less wind resistance)
• don't necessarily require you to buy a more powerful car in order to tow them
  (ie. they are lightweight caravans). I tow with a 1.6 eHDi Citroen C4 Grand Picasso.

... but I'm yet to discover good cheap options for awnings, as they have two rails. Need to research further.
