A bloodmobile may be anywhere from 14-feet to 53-feet long, depending on the platform that it is built on and the type of vehicle that is used to construct the bloodmobile. Mobile blood donation centers are often available in custom sizes and lengths, allowing clients even more flexibility when ordering these vehicles. To figure out what size of bloodmobile you need, consult with a design expert to come up with the optimal floor plan for your needs. You may also work with a project manager to oversee your project and with an installation team to discuss the options and amenities that you need in the vehicle. All of these factors will help you decide what length of vehicle to choose.
