Hi everyone,<br/><br/>Getting ready to buy one of these for our coach.<br/>I can't remember how the drain plug is on our oil pan (coach is 6 hrs away).<br/><br/>Is the drain plug straight down or at an angle?<br/><br/>I need to choose a drainer: straight, angle, or 45 degree.<br/><br/>which drainer did you get?<br/><br/>Thanks<br/>
