I am extremely happy with my cargo drawers in my 3rd gen. I made them low so dogs could hang out on top, and included a flip-out panel so we can sleep on it.
My rig is lifted about 2.5 to 2.75" over stock, but that is mostly because most "heavy duty" spring options are designed for ~3" of lift. I still havent bought a fridge yet, and only have half of my skid plates built (front skid and gas tank), but I am already about 475lbs over stock. I would have liked to lift only about 1.5", but such lifts would have likely been saggy after all the weight.
That said, most of my gear I would do again. I love my cargo drawers (which were something like $75 including two piano hinges). However, overall, Id have probably skipped the winch if I could do it over again, which would have enabled me to build a lighter and more compact bumper.
