hi guys was wondering if anyone has any ideas on this one , i have the hj60 4.0l diesel non turbo auto and it is a very rare vehcle here in new zealand .i recently purchased it from a guy who has really babyied it for the last 8 years awsome condition,due to the fact that i have never driven a truck like this before i am very surprised at how slow it is for its engine capacity , i used to have a mazda marvie 2.6 petrol and it could out tow this in the higher gears the cruizer is none the less very powerful in the low end . i have read many threads in this forum about how good a towing vehcle these are suposed to be,but when i tow the boat or even just a standard trailer it seams to not really keep speed itwill dropp back to 40 to 50 ks/h on the hills even not so steep ones ,and will puf out the black smoke under load or acceleration,but clean as a whistle on start up and normal travel.this all seems very strange to me or am i just being a lttle spoilt and this is just the way these trucks are
