I was using a regular hose bib regulator available at most accessory stores, but I was displeased with the rate of flow at the shower and kitchen sink. I observed the small openings on the inlet side of the device, and decided there must be a better regulator that would not restrict flow, but still protect the hose and plastic plumbing in my motorhome from high pressure.

I purchased a irrigation type 3/4 inch 20 gallons/minute 40psi regulator (at a garden center) and the needed male and female hose adapters (at home depot)for $20. Now I have at least double the rate of flow at both my shower and kitchen sink, limited only by the 5/8 inch hose and smaller RV plumbing.

I'll never change back to the "rv style" regulator!

You did the right thing. After a couple of those small brass flow restrictors almost everyone does what you did. Now you have decent pressure protection in your RV.

Good job! Those "restriction" type regulators do nothing but cut your flow way down. The one I got from Home Depot's irrigation section has a gauge and a knob that can be turned to adjust the pressure from 0 to 80psi. I usually set it at 40psi.

If anyone doesn't use some type of regulator listen to this: when we stayed overnight at the Salt Lake City KOA on our way to Yellowstone, they told us that their water pressure often reached 105psi! Sure death for motorhome fittings.

Not really - they are tested at high pressures like that. But passing the pressure test once does not mean you want to subject the plumbing to those pressures all day every day, so a good regulator is a wise investment.

Me I use a Watts house pressure regulator for my 1 hose hookup. I set it for 50 psi and forget it. The water flows from the hose bib to a whole house filter via a Y fitting, then to the Watts regulator and then to the city water inlet on the rig. The other portion of the goes to the black water sprayer on the rig. I have a back flow preventer attached to the Y.

I built my own regulator from a 1/2" Watts regulator and hose adapters. Works great. They need to change the name on those little inline cheapies to water restrictors instead of regulators.
