Hi from Colorado! New T@B Max S Owners

My mother just picked up her 2016 T@B Max S!!! It's her first camper and she is so excited to go camping in it. So since we are new to the "camper" camping world we could really use some pointers! The dealership didn't help us out too much in explaining how things work, so I have been playing with the T@B and figuring things out on our own. One concern is the counter top between the sink and stove gets pretty warm/hot to the touch when the fridge is running???  Second is A/C fan should be one while running just A/C right?? Once again any pointers/suggestions would help. Thank you so much and are so excited to join the T@B community.
