The Pullrite is great because it moves with the trailer and allow for tighter turns. It comes with a disadvantage though, can't hook/unhook at more that 15 degrees (I think it's 15). I wanted to point that out, in case you have tight spots in your future.
Practicing is a must - but keep an eye on your temperature gauges.
Always as for a spotter and watch for the overhangs, they swing...
And... Watch above... yes, tree branche can jump and damage your roof at anytime... OK, I am re-arranging the truth but I have learned the hard way when a branch rubbed the edge of the roof, puncturing the rubber membrane...
the longer the distance between the tow vehicle and the axle(s) on the trailer, the easier it is to back up... I backed up tent trailers, boat trailers and my 24ft fifth wheel... the boat trailers were the easiest.
My two cents, hope this helps

Something else to remember also, Same trailer but change trucks will cause it to back different also. Shorter truck you have to react faster then with a long crew cab.
Been backing for 40+ years from Tractor Trailers, to cotton trailers, and boats. Its all good as long as you go at your own pace. Plus never never never let people watching make you do something you would not do without anyone watching.
Good luck and just take your time and practice a lot.
