Welcome Mark and Lana, I'm sure you'll enjoy your Eriba.
You say you have camped and camper vanned so I'm guessing you have lots of bits and a good idea of what you need. I would say a sun canopy/shade should be at the top of your list for that bit of protection from the elements, and better than jumping into the purchase of an expensive awning. Have a look at the Fiamma Caravanstore and Isabella Shadow. For a Familia or Puck L it would be a 2.25m Fiamma, For the Familia the 2.5m version of either, a Triton needs 2.8m Fiamma or 3.0m Isabella and the Troll a 3.1m Fiamma or 3.0 Isabella. Used usually available on e-bay but generally cheaper on Gumtree.
