Yeah, I would think cooking in a 13' trailer a few inches from your bed would be a fairly disgusting situation, other than maybe boiling water. I barely cook indoors in my full-size kitchen at home and usually end up using my outdoor stove/grill. I think food, in general, is meant to be cooked outside.
I've actually wondered why it's always the bathroom that's either/or and not the kitchen. I would be fine with a small trailer that had a sleeping area, side dinette, bathroom and no kitchen. But I could only find Clamshells like that-- not Fiberglass Trailers. (EDIT: I take that back.... I did see this thing on Craigslist... but it looks like the equivalent of towing a giant brick, haha... what is it?? http://inlandempire.craigslist.org/rvd/4879457827.html
Do you guys attach your bikes to the Casita
or is there a bike rack on your tow vehicle?
