I have held off posting on the thread until the interior is 100% complete; but it's there now so here is a quart of interior squeezed into a pint (20ft) MH.
VW second row seats and a disconnectible steering wheel means the cab functions as both a cab and dual recliners, plus the driver side has a stop position facing the end of the kitchen counter so that can function as a desk. Passenger side has a wetroom (shower/basin/toilet)
Looking rearward from the passenger seat, we have the kitchen area (combo sink/burner) and waste bin both with glass lid to give around 7 1/2ft of counter surface (fridge, tankless water heater, furnace built under counter, but still allowing draw mounted toaster oven, pan draw, draw for utensils and plates etc). Still leaving a full double cupboard under the sink with shelves for cleaning kit etc. Two twin beds, driver side housing Magnum inverter, power distribution panel (for 12v
and 110v/20amp inverter/generator, sub-panel for 30amp (shore), but also to store the 200watt portable Zamp). Nightstand houses the ducted air-conditioning/heater (we have both gas and electric heat), ducts run through the drivers side bed base and create a circulation inside the cab. This also means no roof air conditioning; that and the regular vent replaced with two Fantastic fans that can also run in opposite flows to create air flow.
There is also enough room in the nightstand to carry the EU2000i generator, which sits on a Low Pro bracket so only have to drop the external door and swing it out for use. The 'top' of the nightstand is also a double leaf pull out table (300lb load).
Passenger side twin base houses fresh water tank, water pumps etc, and some storage, but we also have a full height wardrobe between the passenger bed and the wetroom.
Pretty happy how the whole thing has turned out, and even if we were starting afresh now I dont think I would change anything.
