I've been doing some calling around,here's what Iv'e found. You can get this Apollo system fitted to the new model Kluger,"Premier Auto Center" (http://www.premierautocentre.com.au/index.htm) in Sydneys west have done a couple now. They cost $4495 but you get $2000 back.The 54 L tank is a "Donut Type" that lives where your spare use to be. Where the spare will live after the conversion is up to you. The filler connection goes in behind the fuel cap door next to the petrol filler. Toyota does not warrent anything to do with the conversion but you can buy an insurance policy from Premier for $199 which covers you for anything that Toyota wont honor for the same period as the orriginal warranty. Alternitively if you live in N.S.W. you can go to "Apollo's" website ( http://www.apolloproducts.com.au/index.aspx ) and ask for your local installer. Apollo only supply the kits. At the moment, there is a 1 month wait untill you can get in. The Premier website has a "savings caculator" on it and according to that,I will recover the conversion costs in the first year. The mechanic also told me that the new motor (3.5 L) handels the gas well and they have had no complaints or failures from any of the vehicles with that motor that they have converted. Lets see who will be the first to bite the bullet and have it done...
