Air the bags up with approx. 45psi without the hitch bars installed. Then set up the hitch with the bars per the hitch instructions. In my half ton, I chose to set up the truck and bars so the truck sits in the empty stance ready for travel where this was done to add more mass to the front axle and to allow for more rear suspension travel. All aluminum engines and aluminum sheet metal has resulted in much less mass on the front axle which can result in oversteer, so this strategy has worked very well for me where the truck handles great.
With your 3/4 ton application you will have more mass on the front axle to begin with where shooting for a level truck, ready for travel probably would work for you. What's important is to not set up the hitch then air up the bags. Doing this will result in the bars transferring little to no mass and offering no contribution for anti-sway.
