Just wondering if you've fitted the suspension yet. I'm looking to upgrade my D22.
I fitted a egr block plate just before xmas and ordinarily hadn't noticed much difference in economy but my last tank I just got 739km on a tank.pretty happy with that if it stays like that.
In my d22 tub I installed the camec 59L tank length ways. Which allowed me to build a false floor over top of the wheel arches and on the other side I made a slide out drawer. I installed the lockable filler in the fiberglass canopy and have a pressure pump connect to the tank.
