Hi Paul and Marilyn,
It looks like you made some great choices. The outside shades that Armada sells are great. We never use our old white covers since we got her shades. The Duo shades are also a great improvement over the day/night shade and the v-blinds.
Looking at the pictures of the current 2100, they show small door where Ron is talking about having one put, I guess it is what he is talking about.
One thing I have seen in the pass on other companies 21 ft motorhomes that you might want to consider is a folding floor over the entrance step. The floor folds up against the refer wall when not being used and down in the step well when cooking. A short rope tied to the side by the stove and draped over a hook on the cabinet allows you to pull the step up after use. A latch on the refer wall would hold the floor in place when traveling. Just something I have seen in the pass and thought it would help when cooking and not falling out the door.
We are on our second PC and know how hard it is to wait for that phone call from Stuart telling you it is ready, but that day will come. On both of our PCs I went back to the factory during construction to see it, and ended up making some minor changes. Besides it is fun to see it being built and taking pictures to show our family and friends. It won't be long before you are changing your profile to "Own PC: YES".
