Any suggestions for brand?

Hello all! I am looking for a the best travel trailer for full time living under 15ft. I love small spaces so no worries there and and am every bit a minimalist. But I want the features of a large trailer on a small scale with good lasting quality. I have searched countless brands and have yet to find any model thats would accommodate me. I need a good dc fridge, proper solar (something beyond a trickle), a good clean generator, a shower (not for full time), microwave, stove, sink, DEEP cell battery, separate toilet from shower (asking too much?), good black water - grey water - storage, twin/full bed only (that might make finding room for thi stuff easier) if there were one out there, no room for guests, and maximized storage (just a mini closet please). I am willing to upgrade solar on my own but seriously where is this trailer? I can't be the only one to look for it? I'm not cheap and know what I want but is it out there??
