Hi all, in 2006 they may have been 17.5k + vat, plus extras, being a Prochem dealer myself, I know you wont get one now for that kind of money, if someone pays me 11k + vat - my service engineers will fit the Apex into a vehicle of your choice and I will throw in a 250 litres fresh water tank with mounting brackets & supply pump.
The Everest on 'Fleabay' was not a complete machine (no tools, hoses etc) and had no service history attached to it and the van it was fitted in was a 'Y' reg transit - again with no history, I hope that answers a few of your questions.
