3.0 or 2.7?

[exosteve]

hi peeps. my name is steve and im looking and have been for a while for a terrano.
im unsure wether to go for the 2.7 or the 3.0 deisel manual.
ive priced my insurance and theres only 90 quid in it.
is the tax more expencive on the 3L?
are they all gear driven and not cambelt?
and Iv read the 3L is slightly better on fuel ( which doesnt make sence to me.)
we have had to consolidate this year letting our motor home go then crashing my car. so we decided we wanted one vehicle thats good for work(window cleaning.I know its high up to get ladders on!)
and also with plenty of room for camping gear. but not only that we wanted a toy too. and what better toy than to go places other vehicles cant get too, off roading and of course it means i can get to wales in deep snow for winter mountaineering.
I dont like the idea of towing a caravan so it wont need to pull much weight.
any help or advice will be greatly aprecciated.
steve
