Powermax Boondocker Install
Hey folks, I am replacing my Attwood converter with a new Powermax Boondocker PM4B-60. I am pretty much good to go now, except for the Chassis Bonding Lug on the Boondocker. The Attwood only had wiri...

The chassis bonding lug is wired to RV frame.
If the original "lower portion" converter part of the power centre was replaced with a "deck mount" then you get that confusion. The original lower portion is already chassis grounded by being attached to the metal box the whole power centre is in (the metal box is grounded to frame via the bare copper wire of the 120v 30a input wire to the main breaker etc so the 12v and 120v are both grounded to frame in common)
If you install a deck mount elsewhere (they can go anywhere) then it needs the chassis ground to frame using the lug. Now, if you put the deck mount in as the new lower portion it depends on whether its chassis is in contact with the rest of the power centre's metal box whether you need to ground it again. Easiest thing is to just ground it to frame anyway, since you can have as many grounds as you like, no problem.
