I just went over the entries real quick but here is some advice I learned the hard way. When pulling out of a spot, the back of the rig swings faster and farther than you think. The wheels on a 5th tend to be in the middle and if you turn immediately the back of the rig swings out away from you line of travel. You will hit anything close to the side of the rig. Make sure you have the tires clear of things on either side before turning. I was near a wall on my property and thought I could turn and the rig would follow. It did but the back of the rig engaged the wall. Not a happy day. I have a long bed truck and recommend it over the short bed. If you have a tandem tire set, when backing, make sure you pull forward after backing to take the side stress on the tires. When backing the tires don't track the same as when pulling and side stress is put into the tires and suspension. By pulling forward at least the distance from the tire axle to the tail of the rig you will take the stress off. This would apply to single axle trailers as well.
