It depends on how much you want to spend. On longer trips an alternator delete would get expensive quickly, and once the alternator has charged the battery to full, alternator load is pretty light. An alternator delete would have the most effect on shorter (<1 hour) drives.

My plan (down the road once my current one year old 12v dies) is to have two 20ah deep cycle batteries in parallel with a couple 25w solar panels wired up in parallel to keep them topped off, and a kill switch to manually control my alternator - which is really quite easy with how my Meanwell is setup. Estimated cost is $80-$100 for the batteries, and maybe another $100 for the solar.
