Houston here too. Just took a road trip to palo duro. Less then two tanks round trip at a "decent" speed. Averaged around 27-28 mpg. I want to get some arb lockers, armour, rock rails, hidden winch and fender flares. So far so good no issues. The main speakers quit out on me one day but I let it sit for a few hours and they came right back. Never happened again. Looking to do my own oil changes with filter, any advice?
