fookin transhits, the old type were/are really shite , even worse with any weight in one , the best thing you can do m8 is rip the oil burner out and fit a V8, loadsa grunt , dont have to rev it past 4k , and then convert it to gas , over 20mpg then - i see approx 20mpg fully loaded ( 3tonne van) with another 2.3 tonne on the back ( car and trailer ) pulls like a good un !!

oh and mine an LDV !! considerably cheaper than a transhit !!
