I have the Fiat version and cant fault it , if you want it for a get me out of trouble van then look no further .
Had mine 3 years and had no probs other than the usual consumables .
I have used a pic of when i first fitted it out as it best shows what you can fit in , as said 350 L is the max I would like to put in but it suits my needs .
The tank is 350 upright , the DI is an 8x17 and the poles are SLX 18 and Facelift 42 , the longest colapsed pole it will take is 2 metre if up against roof , a bit longer if running into passenger footwell .
