Recreational Vehicle Lpg Tank Valve/gauge problems of the 2013 Toyota 4Runner

1) the guy who complained about the brake pedal being too close to the gas pedal is right. My foot gets caught under the brake pedal when I'm trying to take my foot off the gas and go for the brakes. I guess I'm still used to my '99 4runner. He also complained that the brake pedal depresses so far that he sometimes also hits the gas. He's right on that too. The dealer says for some reason after a while the brake pedal just goes really soft, pretty dramatically, in my case from the previous day. I have about 27000 miles. Dealer says only remedy is a $125-$150 brake fluid change. 2) the outside temperature gauge doesn't work, so don't expect to be alerted in a timely manner if the roads are ready to freeze over and become icy. Dealer checked it and said it was fine, its not fine. It seems to be usually off by 10 degrees and otherwise reacts so slowly to changes in temperature so as to be useless. Soft brake pedal started in early 2017. Temperature gauge has never worked well.
