my 1986 trooper has the same 4WD axils, springs, and MSG trans as a 4WD luv.
just with a 5th O\D gear and 4.55 gears, not a 4sp with 4.11s
i pulled a 5,500lb trailer to the other side of the country.
and could do 60 barly
my engine is the 80hp diesel with 125 in torque, drove it as a 4sp the hole way

i will note i had a class 3 hitch on the trop with load transfer bars, the wheels of the trailer where VERY far back (helped big time with major side winds) and it was double axil with good brakes on bolth.
if your willing to take back roads or drive at night, and keep tons of clear road in front of you these little beast can move about as much as they weigh
((
with the right equipment and drive style)) i wouldn't think twice about moving a 3,000 load.
you must under stand your pushing the limits of the auto and you must drive it conservatively.
