CAMPING & OPERATING

ONDENSATION

Condensation is a natural phenomenon. The
amount of condensation will vary with climate
conditions, particularly the relative humidity.
Condensation occurs because there is water
vapor present in the air, which each of us
adds to by breathing, bathing or cooking. The
water vapor usually collects on the coolest
surfaces. When the temperature reaches the
“dew point,” the water vapor in the air
condenses and changes to a liquid form. If
moisture is unable to escape the park trailer,
you will experience condensation.

Most people have experienced this
phenomenon when a moisture forms on their
windows. Outside air is cooling the window on
the outside while inside air is warming the
window on the inside; the resulting moisture is
attracted to that surface and the windows
begin to sweat.

To reduce condensation

Proper ventilation and, if needed, the use of a
dehumidifier (customer supplied) will assist in
controlling condensation. Many RV and
marine dealers carry small dehumidifiers
sized for park trailer use. Other suggestions
are:

Crack open windows and roof vents to
allow warm moist air to escape.

When taking a shower open the bath roof
vent (if so equipped) approximately ½”
allowing the moisture to escape.

Use the range hood fan (if so equipped)
when cooking or washing dishes.

Avoid hanging wet towels (or clothes)
inside the park trailer to dry.

If condensation is found in cabinets or
closets, open those doors slightly to
equalize the temperature and provide

The park trailer site must be properly graded
and sloped to provide for storm drainage run-
off. The area beneath the park trailer must be
graded to prevent water accumulation. Soil
conditions in the immediate area are
important. Place pier footings on firm
undisturbed soil (not loose fill) or soil that has
been compacted to at least 90 percent of its
maximum relative density. (Support piers can
also be placed directly on concrete slabs that
are designed for pier loads.)

Climatic conditions must be factored. If
footings are placed on frost-susceptible soil
such as clay or silt, heaving or settling may
occur. In areas where temperatures go below
freezing, the following should be considered if
the park trailer is anchored with a tie-down
system:

1. Construct your tie-down system with

adjustable devices so that strap tension
can be adjusted periodically to
compensate for heaving or settling, or

2. Place the park trailer on a properly

designed raft foundation (slab) or

3. Have the foundation designed so that it is

not susceptible to frost action, and

4. Consult with local building officials to

determine the location of the frost line.

Support Requirements

The design loads used in determining
required pier capacity are 40 psf (pounds per
square foot) floor live load plus the indicated

Condensation needs to be taken seriously.
Ignoring it can damage the park trailer
(damage caused by condensation is not
warrantable), and more importantly could
lead to mold or mildew issues which could
be a health hazard.
