More important than having a check list, is if there are two of you to double check what the other has done.
It just takes a couple minutes but they are well spent.
Things we have caught after the other was certain they have completed all their tasks.
Unlocked storage compartments
Wheel chock still in place
Cooler under the RV
T-pot on the kitchen counter
Dog run lead (we attach it from the ladder to a tree, then attach the long leach to it), still attached.
Fire poker in fire pit.
We have linens for the RV that are a different colour than the house ones. It is easy to sort them out of regular laundry and return them to the RV.
The RV also has all its own kitchen supplies, cookware etc.
Clothing wise we keep a set of basics for the whole family in the RV, so we can go at a moments notice.
We keep pet supplies stocked too.
