Water pressure regulator
Do you use a water regulator? I have one but rarely use, we like good pressure. My take is that these motorhomes use residential type plumbing, so there should be no problem. Is this thinking wrong??

Yes, it's wrong. Our favorite park has up to 120 psi, far above the 60 psi the water system is rated for. Present rig came with a watts built in. On the previous rig I carried one and used it.

Yes...your house gets a consistent supply pressure, you're gonna have a regulator, if it's needed.
The rv will vary. We saw a sign at a park in San Antonio that warned of water pressure over 130psi. Newmar doesn't really expect you to try using 130psi.
I bought a Watts regulator from Home depot...it comes preset to 50psi...I walked an aisle over and grabbed the npt to garden hose adapters for either end and some teflon tape. Works like a champ. Highly recommend.

I highly recommend a Watt's adjustable pressure regulator. I purchased mine from the RV Water Filter Store however.

Hi Hawkeye - If you take a look at where your city water enters the house (if you are on a well then the pump is regulated) you will find a pressure regulator. No one would configure plumbing without capping the pressure. Same for your RV.

50 lbs. of pressure will be fine in the coach for all of your needs. You have received good advice, please heed it. Buy the Watts from Home Depot - or order the same from the RV Water Filter Store. JMHO - avoid the ones with the gauge that look cool and appear better. I was always fiddling with the adjustment which usually changed nothing inside the coach anyway. And then I forgot to remove it when storing in cold weather - no more regulator as it froze and broke the gauge.
Use the Watts. I leave mine attached to the end of the hose, never forget it that way.
Your water filter will restrict your water pressure if you don't change it often. The regulator will reduce the pressure to 50 and your filter if dirty / clogged will reduce the "appearance" of pressure even more. Removing the pressure regulator to improve flow in the coach if your filter needs changing will not work and put you at risk.
Never leave home without it. Could save you thousands of dollars and a miserable experience if you try to NOT use one.

I've always had a Watts adjustable regulator with gauge, set to 55-65 psi on my coaches. On the new coach I wanted to simply the system by trying a new regulator offered by Fairview and sold at the RV Water Filter Store. It's rated at 55psi and simply attaches to the hose end. It's not like the old cheapies that restricted flow and you never knew what they were set at.
Even though the hoses on our power hose reels are rated at 150 psi, I like that this one attaches to the hose end and protects the entire system. It's heavy and well made.

I've been wondering why some buy an adjustable regulator. Because you don't like the stock setting or there's no regulator fixed at the setting you like?

It's not uncommon for regulators to have an adjustment. It lends itself to better accuracy.
We started with the "regulator" that Camco makes. It turned out NOT to be a regulator. What it basically does is shut off completely when it's parameter is exceeded. I had one on our fifth wheel....while staying at Lake Louisa State Park...I would have to go outside...shutoff the park supply...leak down our system...then slowly reopen the supply. A Watts regulator doesn't trip...it just regulates the pressure. It happens to be adjustable...if you want to adjust it. Works 1000x better than the "fixed" models.

Fill fresh water tank..use on-board pump
Simple
No regulator needed, no high pressure excursions etc
Consistent water pressure/flow, easy to turn on/off when leaving, if pump cycles you know you have a minor leak long before it becomes something major etc etc etc
Otherwise.....get a good quality adjustable regulator set it for 50# static pressure (no flow) and USE it.
Course that will not eliminate the minor unnoticed leak from becoming major water damage ......

You are confusing water presure with water flow. Cheap regulators restrict flow unnecessarily. I have a high flow pressure regulator...
Water Regulator, High Flow, Brass, Lead-Free, Carded - Valterra.com | Valterra.com
...and I get good presure at the showerhead where it's needed most. 50-55 psi.
