there are always varying views on this.lots of you recommend big transit style vans and 500-650L TANKS with all the added expense,repair bills,trouble parking,higher insurances etc.
i find a 350L-400L easily enough for a days work on domestic/commercial.with 100m of microbore,varistream,aqua-daptor and a high flow(60).tradding some ground floor windows/doors and i can even fit a few conny roof/fascia jobs in on a long day in spring/summer.although i use outside taps if available.why waste pure water when you dont need to?
a kangoo,connect,berlingo,combo van is big enough for these tank sizes with room for your other gear as well.
cheaper insurance,easier to park on driveways,lower repair bills with a smaller van.
also i do think its a good idea to have a trolley hooked up to your tank instead of seperate pump/controller fixed in the van then you can take the trolley out on very cold nights,detach and use for some work or use in a car with a few barrels if vans off the road so still out earning.also i have some extension hose on the trolley so if parking is awkward for a certain job i can reel a bit off the trolley and point reel in any direction.comes in very handy sometimes.
if you ve no plans to employ there is no need to buy a big van and tank IMO.
thoughts guys please!!
