Congrats on your new rig. First trip is the hardest. If other vehicles are in your way just ask for the owners to move them, never had anyone say no and most will help direct you out of a tight spot also. Last weekend when leaving one truck was parked on side of the road and I could not clear it without side swiping it. Four other campers set out to find the owner who just took off in his boat. Ten minutes later he was back and moved his truck and apologized for being in the way.
Check you sight out before backing in checking where utilities are, kids, low tree branches and levelness. After a couple of trips it becomes second nature. Best of luck and have fun.
