Congrats on your new unit!
There was no warning for our cable bracket pulling from the wall. We’re careful to watch them closely and we didn’t observe anything until it broke loose. Our thoughts are similar to previous posters- carry a well stocked tool box, have an extra cable kit or kits on hand, and educate yourself on how to fix them (the internet is a huge help). Unfortunately, often times it takes something breaking for us to realize what tools and supplies we need to bring along, just in case, so before long we’ll have the entire shop on board
