Someon can tell me how to make trailer right reartire is 2 feet away from the top cone?

Do yer CDL test in Iowa, they don't make you parallel park to pass.

Want a cheat? Get a can of white spray paint. Make a 1 foot stripe on the ground that is about 1 foot out from the cone, parallel to yer trailer.

Then, pull yer truck up so you can see that mark just at the edge of yer trailer in the mirror (when yer tractor and trailer are in a straight line as they should be at that point). Yer tires will be about 2 feet out from the cone. Memorize that view in yer mirror. Memorize that view.

Thats the quickest, easiest way to know what it looks like in yer mirrors. Once you've got it, yer good.

 

The big rectangular shiny thing hanging outside yer right door window. The biggest, flattest mirror you've got outside that window.

Ignore the little round one hanging below, ignore yer nose mirror(s), ignore any smaller mirrors above, ignore everything except the biggest mirror hanging out there.

If you can't see the ground by yer rear tires with the biggest mirror, then either adjust yer mirror, or adjust yer seat, so you can see the ground, that cone and yer new white line.

 

it takes 8' for tire to make a adjust meant.

 

Re-read my post, try it tomorrow, and let me know how it works out for you.

If you can pull the truck up next/past the cones in a reasonably straight line, and the edge of your trailer IN YOUR MIRROR is in line with that white mark, you're there.

If instead, you paint the white line 2 feet out from the cone, and can see it in your big mirror, your tires are gonna be 3 feet out from the cone. Thats just how truck mirrors are.

Don't overthink it, just do it and see what happens.

 

So how'd ya do today?

 

Keep practicing and it will get easy someday. Baby steps.
