Both sytems will suit you fine.
I looked at Brodex last year as well as all the others, Tucker, Ionincs, Skypole and Facelift.
I went for a Facelift system. Mine is a 800ltr system.
Out of the two Facelift will give you more of a discount then Brodex. I presume you are talking to Daniel about the price and what you want. If you Haggle hard Daniel will knock the price down.
They are great systems from Facelift, and Phill who will fit the tank in your van is an enginer and really knows is stuff. I am very impressed with my system, its an 800ltr tank and when fully loaded my van drives superb. Phill also fitted special clamps under the van floor, pic enclosed, These go round the chassis rails underneath the van floor. They are positioned where the tank will feel the impact in case of an accident.
I paid last December to Facelift £3,800.00 incl vat for my 800ltr tank fitted, The tank was manufactured to carry up to three poles on top.2 x hose reels, one with 50mtr of half inch hose, I supplied M/bore for the other reel, 2 x 60psi floejet pumps. 2 x Di Cannister, One 85amp battery. Shureflow Backpack, 2 x mini poles, 1x 18' pole, 1 x 38' pole. Plus a 40 x 40 Ro system on a stand with pre filters and another Di vessell.
I have shown you the price so you can see that their is scope to knock them down on the price. I am very pleased with their system.
Haveing said all that my sons 400 ltr tank should be getting fixed in his van next week at the fabricators. I had help in designing the frame, its an hell of lot cheaper and I will post pics when done but it should look stunning for a fraction of the cost and it will look better then most systems I have seen.
Nel, Good luck.
