I have a question. I am planning move at the end of the year and have a 600 mile drive ahead of me.
I am planning to rent a Uhaul trailer, either a 5'x10' or 6'x12'. Just a one bedroom move, heaviest items a queen mattress, 77" OLED, 180 lbs weights, with everything else not weight much, just taking up space.
I'll probably be driving 65-70 mph+ the entire way since it's a straight road from NorCal to SoCal using highway 5 or 99.
So the consensus is to drive it in 4th gear the entire way instead of just putting it in D and let it adjust gears itself?
I think you should be just fine with that size trailer & load. Not sure about leaving it in 4, but it may be advisable. I pulled that size trailer with a regular cab, 4 cyl. Taco and it pulled beautifully, so I'm sure the 4Runner will handle it easily.
