We have recently purchased a 2008 Swift Charsma 610 T/axle caravan,it has an inboard water pump fitted so there is a hose that goes from the aquaroll into the van (truma fitting on the van),we were wondering if we cun just buy the truma mains water kit from the likes of Towsure or would we need the mains kit for the aquaroll,would rather have the truma kit then we wouldnt need to take the aquaroll with us when we go to main serviced pitches thanks
