Each year we seem to forget something. One year it was to winterize the dishwasher, next was our two traveling plants, then there was the time when the DW left her other pants behinds, etc...
What we do now is spend the first night on the road just 30 miles south. That way we have the whole night to think about stuff, and it's an easy trip back to fix any issues.
Things that are easy to forget are: blank checks, passports, tabs for the RV, Christmas card addresses (if you mail them,) and even when your driver license will expire. Yep, last one got me. Trick is to do the best you can, and not fret too much over the small stuff.
