What Does 'Double Expansion' Mean?

[MacKeira]

In RVs, there can be one or two expansion spaces. 'Double expansion' refers to having two expansion spaces, which increases the interior area of the vehicle. The expansion mechanism in RVs: RVs can be categorized into single expansion, double expansion, and non-expansion types. Abroad, especially in American-style RVs, expansion RVs are quite popular. The expansion mechanism is primarily used in American-style travel trailers, and the expanded space is relatively large. To reduce the load pressure, it's necessary to install supports at the bottom of the expansion area. Pros and cons of RV expansion: It is recommended that for a travel mode of 2+2 (two adults and two children), you can choose an RV without expansion. If it's two pairs of adults with one or two children, you might opt for an RV with an expansion in the dinette area. Increasing the size of the living area can make the space for getting on and off the vehicle larger, making RV life more comfortable.
