Tiny House A house on wheels is the house for me. 40′ long (hitch-to-eave), 8′ 6″ wide (eave-to-eave), 13′ 6″ tall. Estimated dry weight: 12k lbs/6 tons. ERV, 104 gal fresh/gray, 52 gal tank for “dry” toilet, 4kW inverter, 800Ah battery, 700W solar, 90 lbs propane, 1kW propane generator. This is a concept based on the trailer design and wall assembly built by Andrew Bennett at Core Housing Solutions in Tavares, Florida.
