condensation problems. Many of the recommendations will assist in avoiding exposure to
chemicals that off gas.
ALTO trailers have a very high level of airtightness when all openings are closed. It is
recommended to facilitate natural venting during night-time/sleep, even when it is cold outside
and even if the heating is on, to avoid a depletion in oxygen. For example, you can open the cover
of the roof fan without the fan rotating AND open a window about 1 inch to allow a slight natural
air exchange. You will avoid intoxicating yourself by oxygen depletion because your breathing
consumes oxygen and rejects carbon dioxide. A major under-oxygenation can cause asphyxia,
injuries and even death.

ASPHYXIATION,

AND

DEATH.
Do Not Smoke
Finally, we recommend that you do not smoke inside your trailer. In addition to causing damage
to your trailer, tobacco smoke releases formaldehyde and other toxic chemicals.
Medical Advice
If you have any questions regarding the health effects of formaldehyde, please consult your
doctor or local health department.
Warranty Exclusion
Chemical gassing is not a “Defect” in your trailer and is not covered by the Limited Warranty.
Please follow the recommendations in this manual to address this concern.
Weight Distribution
Front, Rear: The 10% Rule
Make sure that when the ALTO is ready to be towed, the tongue weight is between 10 and 15%
of the total weight. There should never be less than 10% of the total weight of the trailer on the
coupling.
A tongue weight that represents less than 10% of the total weight of the ALTO will cause it to
become unstable.
On the contrary, a tongue weight that is higher than 10% will not cause any instability.
The ALTO is designed to be very close to the 10% rule. The placement of baggage in front or
behind the axle, however, can alter its weight distribution. Everything placed behind the axle will
lower the tongue weight. Everything placed before the axle will increase the tongue weight.
Ideally, there should be a balance between both to retain the 10% tongue weight needed.
