I am buying a Pegasus GT65 Rimini and want a front towing cover but they all stop at the top of the "normal" windows. The Pegasus has a panoramic middle window which goes higher and would be unprotected. I have found a company which will extend the standard cover but they need to know how long I want it. Can anyone help me out please - I need the measurement from the bottom of the front panel up to the top of the middle window
