One of the benefits of using a portable garage as opposed to a brick and mortar structure is the versatility. If you ever need to expand your storage space for additional vehicles or other items, a brick and mortar structure is, essentially, permanent and significant modifications may need to get made. With a portable garage or carport, kits can be purchased to expand the dimensions of the shelter to accommodate more vehicles. Typically, peaked roof portable garage shelters are able to be expanded more, and this includes in both width and length. While many of these shelters are designed to protect one vehicle, be it a single car or an RV, these can be expanded to cover more two or more vehicles.
With portable garage kits, one of these shelters can be expanded by adding additional components to the frame and adding a new roof. However, various other models are available to already accommodate two or more cars. These designs can house two cars in a peaked-roof shelter, while others can be large enough to hold four cars. For outdoor events needing parking, some of these shelters can cover up to six cars. But, if you plan on covering a car and a seasonal vehicle like an RV in the same structure, having a larger portable shelter should be designed with the height of the RV in mind.
Aside from the width and length of one of these portable shelters to accommodate multiple cars, a large-sized portable shelter is capable of accommodating multiple seasonal vehicles, including boats and RVs. For the latter, certain taller portable shelters are designed for these vehicles, including both rounded and peaked roof structure designs. In terms of expanding a shelter to accommodate more vehicles, a peaked roof shelter is more ideal in this case, but, specifically for RVs, the length can be expanded to house one vehicle in front of the other in a tunnel-like structure.
