There are two critical factors that need to be considered in order for any porch to suit your caravan: the height from ground level (H) to the top of the awning rail and also, secondarily, if the caravan is long enough (L) to encompass at least half of your desired awning width. Provided these considerations are accounted for in advance, it's likely that your chosen porch will be compatible with your vehicle. As always, please take time prior to the installation date to confirm whether or not access points like windows or doors will suffer interference due to proximity when you erect your new shelter.
