Agree with the previous posters. Take the time to do it right and feel comfortable before you leave. Bring a checklist and your own flashlight, at the very least. For our recent PDI I brought a multimeter and a USB cable to check out all of the electrical and electronic plugs and circuits. I am glad I did since we found the USB charging station wasn't connected correctly. Fortunately, that was the only thing we found during the PDI. Later on we found the fresh water tank drain valve had been left open from dewinterizing. Easy fix, but we thought we had a leak for a while!
Congrats and enjoy your new TT!
