I do tow in 5th in the manual diesel pajero, and usually use 5th at just above max torque of 2000rpm, at about 2300/2500rpm, or 85/95 km/hr. 100 is 2700.
However, I do change down earlier to 4th than I would without something behind, and heavier the load, earlier I change to keep 4th (or the next gear) at the best rev range for power, and the same again if I go down to 3rd, or even 2nd with the trailer sailor.
I try not to lug the engine, and do not use full throttle in 5th, but use 4th instead.
I tow at different times:-
1. 750 kg camping trailer - tows really nicely at 100km/hr in 5th.
2. 1200kg caravan - tows nicely at 90/95km/hr in 5th.
3. 2200kg trailer sailor - max speed about 85km/hr, ocassionally in 5th when level or down
hill. Might do 90 at the bottom of a
hill in 5th, as I like to be slow over the crest and gently accelerate downn a
hill. \/ to the poor people behind, but I do try and keep left and are very aware of traffic behind me.
I always understood from my mechanical text books that bearings are killed by load AND lack of revs.
I change gear box oil on a regular basis too, every 2 years or 50,000k.
Done 263,000k now since new without any transmission porblems.
