Best advice I could ever give a newby is.TAKE YOUR TIME.
You'll find out after a few times, set up and tear down can go pretty quick.
Never ever ever Rush. People get in a hurry and that's when most mistakes and accidents happen. I have seen people try to leave and still be hooked to water or electric. I have seen people take off with their stairs down or their awning out.
Every time I leave, I do a complete walk around. Take 1 minute, stand back and walk all the way around your coach. check storage doors closed, stairs up, antenna down jacks up.
Just take your time and enjoy. Don't ruin a good trip by making a stupid mistake.
