Backing up your rig.

So I'd stay within two to four feet close to the side you going to back into. There's a lot of times your going have one small lane and campers on either side so the closer the better.

So far you have a lot of instructional help here. Here's the way I do it. I approach the spot I'm going to back into, overshoot it a few feet, make a quick turn to the right, to other side of the road, and then a hard left, putting the rear of the trailer close to heading into the parking spot. You should be in a part-jackknife position at this point. This way you are already half way towards the opening that you want to back into. This is all with the idea that your spot is on the driver side of the road. This way you can visually see where you are going. But it takes a bit of practice and you need to find the way its easiest for you to make your maneuver.
I always take a few extra feet to execute any maneuver, alot of drivers don't take any extra space, maybe thy are afraid to.
