For those with a manual aftermarket system, where did you put your fill ports? Suggestions? I'm not interested in drilling anything that's metal on the truck.
finally got to putting the trailer on the ball after installing this kit. went from more than 3" drop rear, 2" raise front with the factory system to about 1" drop rear no raise on the front with the bags at 50 psi.
i need to find a different air gauge, all three of mine start at 20 psi, even the one for my pedal bike. Not sure how to find the low 5-15 psi recommended "unloaded" pressure for the bags.
