The van looks clean and tidy but it is a 2007, with 122,000miles , the plus side is 12mths tax & mot with full s/h. there are lots of trafs with the same same spec for sale at £3000-£3500.
No filters or RO .....the reels are £40 new + hose so £80 for the two, IBC..£40, 2x used clx £120-150 the heater is £200 new so £120, pump £30, water proofing/ checker plate £150
At 7k it it is over priced, I value it all at about 4k-4.2k any more I wouldn't feel like I was on right side of the deal.
