I have a few "must haves" that are still in the package or never used.
Except for chocks the TT came with every thing we needed for a typical trip.
The OP is the only one who knows what their camping needs will be. Most of these are available at Wal-Mart.
I carry an air compressor, torque wrench, jacks and other TT tire changing tools. None of which would be used by a person who depends on road service and probably be of little value to the weekend short distance camper.
Surge protectors, water filters, extra fresh water hoses, extra dump hose, are all nice things to have but people have camped for years without them.
A few trips and the OP will know what their camping needs are.
Two things I will not leave home without are chocks and the clear 45 degree coupling to the dump hose. But that is just me.
