We're looking at spending a year in one, so that's something to think about. Until the summer Camping World sold an under cabinet coffee maker, which would have been perfect. Considering I'm the only coffee drinker in the family we will most likely be getting something smaller and, as suggested, adding a fold down counter extension to put it on during use.
I'll look again but am betting there's a ton of hidden storage in the kitchen; under the stove (or the stove itself, as the microwave is convection), in the island, and over the table. Another suggestion: go to Home Depot/Lowes and check out their kitchen section, specfically the organizers. We have some pot and pan storage racks in our home kitchen that nearly doubles the useable space in the cabinet. Even the lids fit nicely. We lived in a 27' Starcraft non-slide for about 6 months, and had to get creative with storage, like hanging pans on the back of the doors.
Considering this rig also has an outdoor kitchen, we don't plan on being much inside in nicer weather (most of the year for us) so a lot of kitchen stuff will be out there. Saying that, we also plan on limiting size and quantity of cookware to some basics, nothing over 12".
