2 sides to this coin though , if you look at the money you would spend on a trolley and all the gubbins , and put it in your car , then there is the pure water you would have to take with you , in no time at all you will have no space left .
I would at least buy a small van , combo caddy , or the like , put in a DIY van mount , lets face it , the bits from the right places could well come to less than the cost of certain trolleys.
I started with an astra van and a 175L diy mount , this then grew to 425L in a VW T4 , all the parts that were stored have just been pulled from the shed again and gone into my second van , small again combo .
I guess my point is dont make it harder than it is at the start as if it works for you upgrade will come sooner than you think .
