The best has different meanings for each individual. It is important to purchase any product according to one's unique requirements rather than what is normally considered to be the best.

First question that an individual needs to ask is his or her reason for a caravan air conditioner. Is it possible that a regular household AC will also work and satisfy a person's requirements in a similar manner? This is an important question to ask and ponder as there is a significant cost difference between these two. This becomes a vital issue if there are also budget constraints.

There are certain advantages to a RV Air conditioner. It is designed especially to face any kind of environment while on the road. Since a domestic AC does not face a continuous vibration as a RV AC; the former has no provisions for this. However the latter needs to equipped with such characteristics that will help to withstand these continuous vibrations while a van is being driven. Moreover, this type of machine also keeps water from entering AC vents.

Now, as far as caravan air conditioner is concerned; a first choice centers on deciding between a roof top type and a built in style. Since each has its own pros and cons; it depends on each caravan owner to decide as per his or her requirements. The roof top type consumes less space and is usually centrally located for an even air flow. However if a trailer van has a single skin roof then this style may not be a good idea and a built in style should be opted for.

Next thing to consider when purchasing AC for trailer is the amount of cooling that it will achieve. A lot depends on what type of insulation exists inside the van which only a caravan owner will know and not a seller of a RV AC. Pop-Tops are bound to lose more heat due to the vinyl and non-insulated walls and may need a more powerful machine whereas others who have good insulation will cool fast and retain the temperature.

Quantity of amperage consumed by an AC will become important when its power source is the generator. If a vehicle is parked in a caravan park where its fees is inclusive of power consumed then perhaps there is no need to worry about the electrical consumption from a financial point of view. However, from an environment conservationist's point of view; it is highly important to conserve as much energy as possible. It is time that each human being starts thinking and contributing towards energy conservation in his or her own small way.
