1Defective out of the box--suggest you do not buy this product  Jun 17, 2013
By NV_oz
Replaced identical defective regulator (original less than two-years old) on my Keystone Alpine RV. After installation, there was minimal gas flow...not enough to light the furnace at altitude in Colorado. Suburban water heater flame was also minimal with yellow flame. Finally, lit stove burners: minimal flame on one, and unable to light more than one.

After consulting with local RV store and researching online reviews, it seems that these regulators are known to be unreliable. I've now installed a " Camco 59005 RV Propane Double-Stage Auto-Changeover Regulator" (also available on Amazon for less money)...this regulator works flawlessly even at altitude in CO--all appliances have plenty of pressure to operate simultaneously.

5Great upgrade for your trailer  Jan 18, 2013
By David Tullos
We installed an on demand water heater and were having issues with it cutting on and off. The original Marshall regulator would only allow 195,000 btu of gas, 10psi, and 11" water column. This units allows 235,000 btu of gas, 10 psi, and 11" water column. This unit resolved my issues and I now have continuous hot water, even when the range and heater are on.

1Save your money!  Nov 19, 2013
By Charles Lewer
Lasted less than one year. If you buy one, be sure to get two, so you can have a spare on hand.

As a side note, I worked for years as an LP service tech, and it's hard to find one of these automatic changeover regulators made for RVs that last. Most of them are junk! But, I was lured in by the cheap price (even me, who should know better!!!)

I replaced it with a Rego brand regulator, a model that's made for a regular house installation, and paying the bigger bucks to get a quality unit that will last.

5Replaced an old 254-00 regulator with this  Apr 30, 2013
By Drew
My RV (a Chalet A-frame trailer) came with a Marshall Gas Controls 254-00 regulator, which after 10 years was not doing a good job of regulating. Marshall Gas Controls (a different company than Marshall Excelsior) went out of business in December 2012 and the 254-00 regulator is no longer available. This MEGR-8884 regulator mounts and connects exactly as the old 254-00 regulator and appears to work very well!

1DOA -- more trouble to replalce than the low price  May 26, 2014
By R. Bainbridge
Shame on me that I did not read the reviews and got sucked in by the low price. Installed in the late fall and discovered failure on first use of the spring. Amazon took it back without a hitch.

Going to get a more expensive unit -- read the reviews and you will get some suggestions.
