Unimog Club UK

I would just use a length of steel a suitable width for carrying your wheel (something like 9 inch) then have it go across the chassis with some folds to lift it away from the chassis, so that the wheel is stored horizontally. Remember to use existing bolt holes, as drilling a unimog chassis can cause it to tear, the problem is reduced when you dont have a lot of weight on it, but i still wouldnt risk it.

If i get the time, i will do a drawing to describe what i mean.
