The advice from fellow FRF members in this forum is top shelf. Check lists for me are important and everyone approaches each experience a bit differently. As an example my DW and I developed the check list below for our arrival procedures.
Arrival at site
o Select level area (give room for slide-outs)
o Set landing boards for tires and level (side-to-side)
o Hook up shore line w/ serge protector
o Unhitch TT
o Level front to back
o Hook up water line with filter and pressure regulator (run hot water faucet make sure hot water tank is full)
o Hook up sewer lines
o Check refrigeratorů. Auto adjust temp.
o Set hot water heater to elec.
o Open TT (take out two beers)
o Open awning and tether
o Prepare site (chairs, etc. enjoy beer)
You can take all the info in this forum and start developing your own check lists. They will keep you organized and lessen the chance of "screwing -up" BUT we have all done once or twice.
