I reckon the only thing against the suby on the beach is the relatively low rolling diameter of the tyres.
The plus is the light weight.
Embarrasing thing was I went to Butty's with my neighbour (petrol Jackaroo). The suby went out and back, got stuck ones and a push and a few revs and she was unstuck.:D
12 months later went out to exactly the same place with same neighbour in my then new D3. Compressor failed!:(
