prepping for 1300 mi trip

Ok it sounds like we were on the right track. We were planning on half tank fresh for dishes, flushing. We drink bottled water and will have that in tt. Already researched potential overnight CGs and are planning on wheel bearings etc maintenance today. Just wanted to make sure I wasn't missing anything. Of course I'm a little worried about the tv because I just got it back from the shop. It has been having an intermittent power loss and dealership couldn't replicate or find he problem. Running sea foam cleaner through it now to see if that resolves that issue. But its had all its recent oil change, fuel filter change etc. Thanks again all.
