New guy needs some help!!

The bed is fairly easy to remove. Eight bolts and the wiring should be the only things holding it on unless something has been added. Sometimes bumpers lack clearance, but you can check that. We try to have (4) people to lift it off or we have used
two chain falls at times

It sounds like you have not got the rear brakes bled completely.
The prop valve can interfere when you bleed the rears. We usually bleed at the line where it connects to the prop valve and then bleed at the rear wheels. We use submerged hoses to avoid getting air back into the system and then just pump until
the air bubbles are gone. At the front we hook a hose up and submerge it into the master cylinder and pump gently, (if you pump hard you can shift the valve in the prop valve).

At the rear wheels we put the hose on the bleeder and put the hose into a container of clean brake fluid and then pump the brakes. A power brake bleeder also works well if you have one available.
