We had to lower the front shade a few times, about a foot, to block the sun. It hasn't been a problem. The big windshield was was great when we went through the Badlands and the Arches.
I was happy to see no oven when we bought ours. We use a countertop convection oven, and the microwave, for everything. We never used the oven in our last motorhome.
Definitely downliad Ed's manual. It's a goldmine of information.
