Added the Airlift bags to my truck to level when towing my 5th wheel. Easy to assemble 95% on the workbench. Removed tires and spare and took 10 minutes to install the rest of the way. Airlines took longer to install because I wanted them to not rub. kink or bend. Overall about 2hrs to install system, run airlines and reinstall tires. Brought the schrader valve out through license plate mounting hole and used airlift tee to connect hoses so both sides inflate to same air pressure at same time. Make sure to push airlines in all the way on all fittings. Pressure tested and no leaks. Gunna see how well it works this weekend pulling 5th wheel.
