Genuine Webasto Air Top Evo 55 Heater complete with installation kit, only thing it doesn't have is the original box. These heaters will have attached an L-Shape bracket for mounting, temperature control and everything else listed below to install. Any other part that I didn't list below is only because they're attached to diesel heater already. Yes, this is Genuine Webasto.
