I have drove an 18 wheeler for a min. I had no lic. and no clue . I just wanted to try it. I got car sick. hahaa
Have you granny, I've never driven anything that big but did go with my Dad when I was a kid in his.
I can just about mange my little van and the pick up but that's it!! Then again I've reversed my van into a few things in the past

Don't think I could be trusted with anything bigger!!
