I’m torn between the AR3 Essential and the ARX+. We mostly do campgrounds but want to try boondocking more.

Hey Kevin, if most of your trips are still campgrounds, the AR3 Essential filter kit # GB39FR is definitely the easier day-to-day setup. It’s built for pressurized hookups and comes with everything you need.
The ARX+ # GB54FR is really geared toward off-grid use since it has its own pump and battery to pull water from a tank, lake, or container.
One thing that’ll really help narrow this down - what camper are you running, and does it already have a 12V water pump? If it doesn’t, the ARX+ can actually fill that gap since it handles both pumping and filtration in one system.
Are you planning to build out more of an off-grid setup, or just testing the waters on a few trips first?

Thanks Andrew! That makes sense. We’ll probably stick with campgrounds this year and just try a couple off-grid weekends. Sounds like the AR3 is the better starting point for us.
