Tim,thank you very much !
Camping World does have the best price but they denied warranty with DIY installation. And if you add the labor price...
But Camping World is the only place that warns about having to buy a door panel separately.
In my opinion it is completely insane to sell unfinished product especially very expensive one.
I am going to check with Nomadic Supply .Their description of the product mentions "optional" door panel to fit any interior design.It sounds like " if you do not like our door panel color you can purchase a different panel at our store".
