Ouch! Tough way to start with a new camper.
I am guessing that the rear of the camper swung out when you were pulling out, and that is why the awning caught? That is a looong camper, and it is hard to judge where that rear end is at all times.
As for the broken thumb, a painful but good lesson to read instructions before attempting repair!
The fridges in those rear outdoor kitchens are notorious for dumping their contents all over the place. Anything in the back of any of these units get quite a ride on our "wonderful" roads. Funny they don't have a lock for those fridges.
But it sounds like you made it to your destination safe and sound, and if the remote is the only problem with the camper, you are doing good!
Now it is time to relax and enjoy!
