Just be careful in doing this. My spare wheel weigh's 27.2 Kilo's and will be subject to a fair amount of vibration and impacts when going over ramps potholes etc. With my setup the energy is absorbed on the rear chassis where the tow bar is fitted and not the fixings that hold the carrier to the Motorhome.Philippft, thanks for the idea. I did consider strapping the wheel to my Fiamma bike rack which would be very easy but only practical when I'm not carrying the bikes. Nevertheless it could be a temporary solution to think about if needs must.
