If you look at the front and see the fog light, it has the upgraded features. Larger screen, sat radio, Mercedes nav, and more.
The options include Li batteries, front seats same as chassis upholstery, levelers,dual pain windows and diesel generator.
This is a very expensive motor home. To the cost you need to upgrade the chassis. Borg tire valves, TPMS, Fox Shocks, alinement, maybe sumo springs and Sway bar.
If you want to boondock you may need the LI battery, a second panel and diesel generator. The refrigerator is a power hog.
I love the D models. The coach is open, bath is nice, one tv so now we will fight over channel.
My 15 G is good enough for me, the upgrade cost could run 60k maybe more. Crazy.
