The Onan 8,000-watt generator mounted on a powered slide out system enables the lower portion of the
front cap to extend with the generator for ease of access. An Onan EC-30 automatic generator start module will auto-start the
generator should the battery voltage fall to a preset level or if the thermostat calls for cooling when shore power is not
available. A Precision Circuits energy management system sheds loads as needed to prevent tripping the pedestal breaker when
on 30 amp shore power and also interfaces with the dual 2,000-watt Magnum true sine wave inverters to provide additional
capacity. A 50-amp power cord reel is located in the basement for ease in connecting to shore power while a Surge Guard power
monitor watches over your valuable electrical components. A bank of eight, six-volt AGM batteries provides ample power to easily
meet the coach's 12-volt needs.
The plumbing service bay is equipped with a whole house water filter, a waste management pump, an
integrated black tank flush attachment and outside sprayer as well as the usual assortment of valves and controls.
Coach heating and domestic hot water is provided by the Aqua-Hot hydronic heating system which uses either
diesel fuel or electricity to heat the boiler to provide comfortable heating and unlimited hot water for long showers. The burner's
exhaust is routed to the rear of the coach rather than to the side due to the full wall slide out. The Aqua-Hot boiler is placed
at a right angle to the usual installation because the 150-gallon mid-ship fuel tank location doesn't permit a lateral installation,
which makes it a bit harder to access for service work.
Our coach was optioned with a 90-inch dual acting cargo slide tray in the first full storage bay that could
be accessed from either side. The second bay held a pair of 36-inch and 54-inch cargo slide trays so that one tray could be accessed
from one side without affecting the other side, allowing taller cargo to be placed there without worries about hanging up on the
frame rails. Although, with a 22.5-inch clearance between the bottom of the I-beam frame rails and the floor, there's plenty of room
for most large items.

The 8,000-watt Onan generator is mounted on electric powered slide rails. The lower portion of the front cap is mounted
to this framework to afford maximum access.

This coach was equipped with a 90-inch double acting full width cargo tray in the front bay and a pair of split
cargo trays in the second bay that can be accessed independently of each other. Side hinged doors with power locks
provide ease of access to any basement cargo.

The last curbside compartment places the air dryer, fuel filters, batteries, DEF tank and other service related items in
one common, easy to access location.
