Installed the bags.took no time at all. easy to do. Took measurement of rear ride height with bags empty. Hooked up trailer used air to bring up the trailer to about same ride height. Hooked load leveler bars up. Dropped two links down on the chain. If I went up to the same link with out the bags it jacked the truck way up in the back. Down two links and bags filled to 30 to 35 lbs. ride was good truck and trailer level. O' and I ran the air lines like the others, to the plate holes. NO ISSUES . Just don't like the white colored plastic caps. They really stand out. Gona steel some black ones off the kids bike.................... Thanks for all the input.
