Pretty amazing setup.
I was thinking I could solar water heat in summer sun simply by plumbing in a bypass to the water inlet and putting a hose loop down. Even with a white hose from the full hook up faucet, the cold water coming in at 106 degrees out and sunny was within a few degrees of the temp of the hot water from the tank until it flushed through the hose. It would be pretty easy to take advantage of all that solar water heating.
On tires the problem I am seeing is the hot roads harden the tread polymer (cook out the plasticizer) and make wet road traction poor. The tires last too long rather than not long enough. It is amazing how much better new tires grip in the rain the first couple of years compared to 4 or more years of very hot summer roads cooking them. That's something I never saw in colder climates.
