Is it OK to use the Earth Post and Positive post on the right side of the engine bay to trickle charge the battery ? - 2014 E550 Cab

If you're referring to the battery connections described in your owner's manual as the jump starting terminals, the answer is yes -- connect your maintainer there. If your battery maintainer came with a short pigtail cable -- eyelet terminals on one end and a polarized connector on the other end -- it's well worth the few extra minutes to install it, as it ensures you'll not accidentally connect your maintainer backwards.
