In reading the notes on the side of the TM near the tire cover. It says to ck the proper tightness of the lug nuts. I got my TM used and could not find infor as to the proper range. I will borrow my neighbors torque wrench and check them.
I have read 70# and I've read 90# (I believe that 90# is correct). I torque mine to 80# and check them often. I broke a stud on another camper when torquing to 90#.
