2.1 locatIon and support

2.1.1 generator locatIon

The most desirable location for the generator set is

between the vehicle's main frame members. However,

this is seldom possible. Most units must be installed

on the side of the vehicle and are difficult to rein-

force.
Many recreational vehicles have been factory equipped

with an area for the generator set. Some vehicles may

even have a generator compartment provided by the

vehicle manufacturer.
Plan the generator location based on the following:
• The generator set must be installed on a frame-

work that is part of the recreational vehicle, as

outlined in Section 2.1.2.

• The location must provide an access opening

that is large enough to permit generator removal

(unless the generator is to be removed from under-

neath the supporting framework).

• The location must provide easy access to frequent-

ly serviced components, such as filters, oil drains,

spark plugs and other common maintenance

parts.

• The location must provide sufficient room to allow

minimum clearances as outlined in Section 2.2. If

sound insulation is to be used on the compartment

walls and ceiling, the minimum recommended

applies to the space between the generator and

such insulation.

• The location must provide adequate cooling and

ventilating airflow for the generator without a great

deal of work and expense.

• If mounting the generator in an enclosed compart-

ment, the base of the generator must rest flat on

the floor without any gaps.

• When using a suspended mounting system, ensure

the base of the generator is flush with the sur-

rounding bodywork. If the unit is mounted higher

in the structure, heated air may recirculate into the

generator causing it to overheat.

2.1.2 generator support

The generator must be securely attached to a metal

framework that has been made part of the vehicle

frame structure by bolting or welding. The metal

framework on which the generator will rest and

which will restrain the generator set should consist

of at least two horizontal beams. These beams should

consist of (a) 1-1/2-inch square, 11-gauge steel tub-

ing OR (b) 1-1/2-inch, 11-gauge angle iron. A typical

supporting frame with horizontal support tubing, is

shown in Figure 2.1.
The generator can be installed so that it sits on top

of the horizontal support tubing if the vehicle design

permits. Another method is to suspend the genera-

tor below the horizontal support tubing by means of

suitable, structurally sound metal framework. The

following general rules apply:
• Vehicle construction MUST be capable of support-

ing the weight of the generator.

• Whether the generator is mounted above the hori-

zontal support tubing or suspended below the tub-

ing, the supporting frame used must be structur-

ally sound.

• If the generator cannot be bolted directly to

the supporting frame or support tubing, con-

sider using additional tubing, angle brackets

or other supports to give the supporting frame suf-

ficient strength.

2.1.4 generator restraInt

Use four 5/16"-18 hardened steel bolts (Grade 5) to

fasten the generator to the supporting frame or the

support tubing. These bolts must pass through (a)

the generator mounting base, (b) the compartment

floor (if a compartment is used) and (c) the support-

ing framework (Figure 2.2). All bolts must be long

enough so that when tight, at least three threads are

visible past the retaining lock nuts. Refer to Section

2.2 for the location of the generator mounting holes.
