I was told the "Elite" mean that the coach in question... has the super sized slide from the cyclone toy hauler line. That of course would mean it would have the straight roof line due the height of that slide. We have the a 3260 which has that same slide. Lots of windows and light with all those big windows.
We bought the 2017 Bighorn 3760 EL in the beginning of June, 2016. The roof line is only straight in the 2 LR slides and has coffered ceilings in the LR. I do believe EL is translated to "elite", not sure what makes it elite. The slide is 7' tall with the power recliners and we love it. We do have the residential refrigerator. No LP backup. However, it has 2 batteries that work flawlessly to power the refrigerator while traveling without shore power. Longest trip 14 hours with no shore power and refrig and freezer never lost a single degree in temperature.
We we do have lots of windows, with dual shades, one for sunlight, one for darkening. King bed and full sterling paint. It's a beauty...we love it!
