Well congrats first you will enjoy the Ollie and all it has to offer. You have a good start but a couple of things such as extra hose for washing out the Black tank not to be used else were, 30 amp extension I have needed this a couple times, Dog Bone or reducer at least 30 amp to 20 amp and I have needed also the 50 amp to 30 amp reducer for electric hook ups, lock for the lever on trailer ball if it is the Bull dog you need a small shank lock not to much to worry here there is a Tractor Supply store just up and across the street from the pick up location and also a Walmart I would stay in the area a day or so to check things out. Pillows, covers, towels,etc if you did not get the beds I would have some memory foam or something for the the beds. Safe travels and I'm sure others will help with more recent deliveries. Thanks Gary
