We traveled over 20K miles on our 'china bombs.' However, if you still have the original tires on your 2007, it is probably time to get new tires.
If you check your tires at each fuel stop, there is no need for remote monitors. Especially if you have newer tires. I would spend the money on new tires rather than a monitor.
We have an air compressor. In our seven months of living on the road, we have used it exactly O times. In our 4 years of travel before that, we used it once.
We always travel with our fridge on using propane.
While the a/c filter might look clean, it is probably a good idea to clean it with soapy hot water and bleach. The amount of dust I got out of our 'clean' filter surprised me.
As posted, check the screen for the water pressure.
There is no mount I know of that doesn't use screws, both into the wall and into the tv. With a tv that small, you can place it just about anywhere if it is an LED.
Best of luck! Sounds like a wonderful trip!
