Exhaust vents

A 355mm ceiling opening was reinforced with alloy box section and a Maxxair Maxxfan Plus with Thermostat control, Power Lift tilt, Rain Sensor and remote control was fitted



A pair of mushroom style alloy vents painted with matching vehicle paint have been used for the bathroom exhaust fan and the vent for the refrigerator, microwave and hot water heater cabinet. A solar powered fan will pull warm air out of the cabinet that will draw through a grille on the bottom front of the cabinet.  





An exhaust fan was added above the cooktop area for the rangehood, a Dometic CK155





Overhead cupboards

Our plan for the overhead cupboards is to use alloy bracket supports wrapped in light weight shelving and with vertical cupboard doors.


Collection of alloy T extrusion parts before being TIG welded


L brackets after TIG welding and drilling for mounting holes


L brackets held by top cross bolt attachment


L brackets secured with both top and side attachment



Bolted into a pair of Rivnuts inserted in the side of chassis inner skin




Cupboards dividers fitted to prevent contents moving too much under heavy braking or acceleration! 


Custom sized overhead cupboard panels and doors were sourced from Standfast Kitchen Kits and are made of Laminex's light weight 16mm  V-Lite Foamed PVC panels to minimise overall weight but particularly near the bus' ceiling to keep the centre of gravity down and minimise any handling compromises a top heavy bus would otherwise display.
