Good idea to set up and rest a bit but try not to stress on too many things. One big idea is that whatever you find doesn't work---probably does if we can just find the right way! And over time, things begin to make more sense. As you light off the furnace, listen to what you hear as it does things different than at home. At home the fire lights and heats before the blower comes on but in RV it is just the opposite, The blower comes on immediately so make sure gas can't build up if the fire doesn't start. Just small stuff that WILL make you scratch your head a bit. No big thing if the weather is reasonable and you can often just ask the guy next door and they may have the answer right away.
Best of luck, be safe, and enjoy!
