1st TT arriving tomm, what is your check list for setup?

I would not accept the trailer without making sure everything works on both shore power, generator power (if it has it) and that those things that work off battery power function correctly. Does it have slide outs? Check these. If it comes with a generator make sure the transfer switch on the generator works correctly. Ours did not and we almost burned our RV to the ground, and would have if I had not found this installation error.
