There are lots of alternatives to an outside kitchen for what you will most miss (the mini fridge).
1. Regular cooler
2. 12v cooler
3. Propane cooler
4. 120v mini fridge
Any of those could store in the outside storage and then get set up outside when you get to your site. As wowens79 is doing, a mini fridge with power in the outside storage compartment could give you what you want.
You could easily get a double burner cooktop and a table that could get set up outside also. And you'd have the versatility to set it up where you want - instead of always having to be "right there".
You really don't care about the rest of the outside kitchen, so go simple. Get the RV you like and create your own outdoor "kitchen area".
