I've a series II Discovery HSE 7 seater. Looking to go off road camping in Australia. Want to know best options for snorkle for my model (inc any advice on fitting), and how to remove the 2 rear seats on my 7 seater to max the load space in the boot. Any advice gratefully received.

 

if dealing with a lot of sand /airborne dust it is good to the head facing towards the rear.
fitting and price is usually easier and cheaper with the ones that have the larger portion on the exterior running along the panel. imo the little extra $ for the mantec and that style (just the stack running up the pillar) is worth it, from an aesthetics standpoint. install is fairly easy with both styles and you are accomplishing the same goal. so I would find the one that looks best, to you. my vote mantec

 

There was a knock off on eBay for a little over $200. British4x4 is selling a TJM snorkel on eBay for $339 + Shipping.

You can remove the rear jump seats. You will need new trim panels. Check with Paul Grant. He is a dismantler and he is on this forum.
STC50446 is the p/n for the thrid row kit. Here is a link to the install instructions. http://www.pm10000.webspace.virginme...nstruction.pdf
This should give you a good idea of whats involved

 

I have the chicom snorkel, 189 on eBay, you are in Australia ? Think safari snorkel is made there? For dust you want the top that is a clear pot
