A customer mentioned them to us.
They told him they would fit a complete system in just one day, which included prepairing and coating the floor (what about drying time) !!
Its not practicle or possible to do the job properly in a day - well it is possible but that would mean no checks could be carried out on the pumps,charging relay, RO/Di, and no time to run the unit to check for leaks from poles,fittings,RO etc. Even drilling the floor pan and prepairing and tightning the tank securing bolts, plates and chassis correctly can take half a day if the vehicles fuel tank needs dropping to secure the water tank that part of the job can and often does take a full day.
