The filtration “system” I see a lot is a blue external filter that goes between the RV park faucet and hose connection on the RV
Generally we don’t drink the tank water, bottled only.

Regarding the sway bars...
We have Helwigs on front & rear, plus air springs in the front. Also SUMOs to bump stop if needed. And I just received a new set of Bilstein front shocks.
All purchased on Amazon&DIY installed.

My rig is completely outfitted now:
- HWH Levelers
- 1200/2000 watt inverter
- 300 watts of solar
- two new batteries (still haven’t changed out my chassis battery, knock on wood)
- Progressive Industries hardwired 30amp EMS
- Winegard Trav’ler satellite dish with DISHnet for the 3 TVs
- spare tire&rim under the rear
- and when we go for a week or more...we tow a Chevy Spark 4 down & carry two bikes on the dual hitch

My tires are in good shape at 22k, but are 5yrs old. So the fear-mongers on the Forum insist that I change them

It’s easy to catch the RV fever

We are taking a trip to Washington state in September. By then I want to have installed a front sway bar, rear helper springs and a water filtration system. I think it was Judge that hooked up a FW tank fill valve from the city water connection. Might do that, too.

Nice.
Good purchase
Looks like you're really getting-into this RV thing. Hahaha

I just ordered a Watchdog EMS from CW. I like the Watchdog in that it has a Bluetooth app and I don't have to figure out where to mount a display. Got it for under $200 delivered!
