We are making almost the same chassis and drive train. We have a tower for the totes to up and down on. We chose to have the center of gravity to be slightly behind the center-to-center distance of the two drive axles by changing the location of our tower. That way when we are loaded we have our weight more forward, but too much. This does mean sacrificing strafing capabilities unloaded. Hope this helps!

Edit: I noticed that you are using VEXpro gears outside your frame. I would definitely be careful with these; Team 1986 Titanium had issues with their gearbox being outside their frame. These gears need to be lubricated properly or else you will have a lot friction in your drivetrain. You probably also want a shield beneath your gears to protect them from carpet and other robot parts
