Congrats on the new adventures in RV'ing. I agree with another post about only putting cold food in the fridge. We always turn our fridge on the day before we're leaving, and wait until it is cold (I have a thermometer in the freezer) before loading.
During our stay, the black tank dump valve remains closed, allowing the "contents" of the tank to more completely liquify before emptying. Depending our the length of our stay, may not need to dump it before breaking camp. Day before we're going to leave, I will go out and close the gray tank valve, to save water for dumping after the black tank.
Then I'll connect the dedicated water hose used only for tank flushing, to the black tank fill, while DW saves a kitchen sink full of hot soapy water. When I have finished dumping black, then gray, I'll tell her to go ahead with emptying the soapy water, which will drain thru the gray tank, and sewer hose. Follow with a rinse from that dedicated garden hose, and we're done.
Sounds like a lot, but doesn't take long al all. BTW, I suggest using a pair of disposable rubber gloves when handling the dumping chores.
If you're having trouble with the awning, the arms may not be lined up right, due to the fabric having shifted left or right on the roller tube. Have the dealer or someone else knowledgeable, go over the procedures with you. It souldn't take but about 2 minutes to open or retract the awning.
