FW Discovery LXE vs HR Endeavor

[RVinDoc]

So I have read all the threads related to these two talking about how they are essentially the same RV and all.
However, what is the deal with the roof of the Discovery LXE? Nothing on any of FW's websites discusses it, and non of the dealer videos showing all the features mentions it.
Thanks in advance for Info!!!!

Wife and I went thru the Decatur IN plant 1 today. Very good 2 hour tour. Learned how motorhomes are put together. Saw several Discoverys. The roofs are fiberglass. The construction is sound. Well put together.
Supposedly there are 9 inspection stations. Could not confirm. Doubt it's effective. Based on my experience.
Takes 4 days to assemble, several more to paint. Motorhome put out every 39 minutes. If they were not assembled quickly our MHs would be much more expensive.

If you dig through the information on Fleetwood's website, I think you'll see that the LXE has roof-mounted Girard awnings instead of the more common wall-mounted awnings from Dometic, etc. The front and rear caps are molded to integrate with the Girard awnings, giving a sleek and tall look like many higher-end coaches.
