Two questions I always forgot to ask that no one talks about

i am not understanding the first part, the bumpers are there to soften the blow and reduce damage to both truck and dock

the second, my personal experience is not to drive in tranny-lock mode, but leave it at single wheel pull, i can maneuver better in the ice and snow when i can judge where the pulling will come from

whenever i have tried to drive with the differential lock on, i always felt like i was going to spin out

there is no all-wheel, its either one or two wheels pulling

 

For number two, he may be talking about driving with just the two wheels on one axle powered or powering all four wheels

 

It depends on how hard you "bump" the wall and how strong the wall is. what do you mean by "all wheel drive" having the rears locked together? NO not good to run down the road with the rears locked together.(Inter axle differential engaged). Did you notice that I spelled axle correctly?

 

What is tranny lock mode I am at such adisadvantage by being old because I never got to go to truck driving school to learn all that high tech lingo

 

if you just tap not bump you should b in good shape. not a good idea to run on the highway with the dif. engaged, good way to drop the drive shaft. jon

 

Buy a good padlock and forget about backing up to a wall because sooner or later you will damage a wall.

 

Think about it...What is going to happen to the wall and your trailer if you keep bumping both??
If you are 6" from the wall, how can anyone get back there to open the doors?

The axle interlock does you no good on icy, snowy, or slick roads
