The reasons I recommend NOT adding for options:
1.The market price is "as typically equipped" rather than strictly by factory base price. Dealers and buyers are more likely to deduct for missing amenities than to add for things that may have originally been extras.
2. The options list has all conceivable things an RV might have, but the "year notes" do not define in detail what was standard or not. It usually mentions a/c, tv, and a few appliances, but typically neglects many other standard features. For example, one NADA entry I looked at mentioned the coach has a stovetop, oven, and water heater as standard, but neglected to mention the refrigerator or furnace or microwave (all standard in that model). If you went by their list, you would be adding all kinds of options that were in fact 100% standard.
3. Most options are personal preference items and do not have universal appeal anyway.
5. And the dealer doesn't add anything for them when you trade in!
That said, on a basic unit there may be an option that is a big ticket item and fairly unusual for its class. For a Pop-up, an air conditioner is often a significant add-on item. So might an awning, since most pop-ups do not come with them or have them installed. So, use some judgement. If the item is of significant dollar value and wide appeal, add some value for it.
