Welcome! And thank you for your service! If there is a question you have, you’ll find the answer on here!! Being new to rv’ing, the 1st thing you need to invest in, is a tire pressure monitor for your rig!!! I’ve seen a lot of people get tire blowouts that do thousands of dollars in damage to the side of their Rv! Remember, most of the time you will never know you have a leaking or flat tire until it’s too late!! I bought this kit for mine..great reviews, works great, and piece of mind!! TST507FT4C. Look on Amazon..Tst 507 Series 4 Flow Thru Sensor Tpms System with Color Display
