Over time and looking at lots of drawings for different RV, there is one thing that seems to often be open to having options and that is the radio/entertainment centers!
That is one of the things which has the most options because the electronic area is changing so rapidly!
That leaves me to guess that what you are asking will be open to too many questions until actually dealing with the sales process and possibly ordering the options you want.
Much like car shopping, RV can get tricky when we begin to price different units at different dealers. You may price "exactly the same" at one dealer and then find it cheaper at another. What you may not notice is the small stuff like what entertainment option you get!
This is part of the options list for a 2016 model that involves the radio/entertainment system. With this number available 7 years ago when we were kind of just beginning to add "gizmos", think of how many the newer models are likely to have?
With early and late year builds and so many options, I see no way to predict what each RV will have.
The only practical way I see to compare one RV with another and look at the small details , is to get the line item sheets for each and lay them side by side to check each line!
If you've looked at a car list, you can begin to imagine how many more options there can be when we add a whole house on top!
Having grown up around car dealership families, I know one of the tricks of the trade is to have a few that have few of the options and that allows you to honestly sell them cheaper than the guy in the next town who has more options on his.
When it hits the fan is when folks bring their cheaper version to the dealer selling the car with more options and complains about the quality of his cheap seats!
The same applies to RV but in spades! There is simply no way a normal person can walk through an RV and spot the options differences!
