The cabin on wheels is finished!
Well it’s been 2 years since I begin framing. The cow has already logged in over 8k miles on the road. She tows well.
Utilities hookups are the same as an RV. Everything crucial runs on 12v batteries and propane while off grid or driving.
The tiny house puller is a ram 3500 flatbed with a custom removable aluminum shell that I built. 
The kitchen features mahogany counter tops, hammered copper sink, propane 4 burner stove/oven, microwave, hoodvent, propane fridge, hickory cabinets with lazy Susan , led lighting, and mason jar storage shelfs.
Sleeping loft has a retractable aluminum ladder, cedar beams and beetle kill pine floor arched window and ceiling, custom cedar and wrought iron railing.
Living room has memory foam L couch with storage underneath. Mahogany coffee table and a 5ft projector screen. Storage above hallway. Floors are solid Koa wood throughout. Cedar walls with custom stain color pattern.
Bathroom is equipped with claw foot tub/ shower, record player Mexican sink conversion,medicine cabinet, standard flushing toilet, washer dryer combo, on demand propane water heater and a custom barn door style slider.
And lastly this house actually has a floor level bedroom. Queen size bed with storage bins underneath. 
There is a “shed”on top where I can store hoses, sewer lines, and other stuff out of the way. Always an adventure hooking up to utilities and getting fuel. We really are loving this lifestyle. Video tour is in the works. Stay tuned for more!
