Re: rear suspension
With 1 inch of travel unladen, you need to notch it. I'd imagine if you bounced on the rear of the truck your body weight would bottom it out currently and you probably weigh a lot less than the motorcycle does.

Drop springs, and lowering blocks? Did you add an adjustable track bar? Did you add rear shock relocators? Personally I would add the c-notch and swap out the coil springs for some 2600 air bags on schrader valves. Then you can air up any time you need to haul anything. Plus you would be able to use quality shocks. I’m not a fan of air shocks.

Re: rear suspension
With only 1" of travel, air shocks won't help enough

Re: rear suspension
C Notch and air bags. Even if you do what I call a pipe notch, you gain at least 2 more inches of travel without cutting into the floor. I would also box the frame in that area for more strength.
