MARSH EXCEL MEGR253H Marshall Excelsior Reg 2-Stage Auto Vert Bulk

This regulator is well-built and works well. It switches from empty to full tanks automatically, as designed, and flows plenty of gas for my 40k btu furnace and stove/oven.

replaced an existing regulator on our RV with this regulator. I had to fabricate a bracket because the existing would not fit. But it was worth the extra effort because this is a better regulator.

Works great, switched over just as it should when one tank was empty. The price was great. the product is great Used it all winter here in Wisconsin and didn't have any problems. Used it for a hot water heater and a 40,000 BTU furnace. .never had a problem seeing the green/red indicator. Very pleased with product.

This product works really well. The only thing to be aware of is you will need to get #10 1inch self tapping screws as they do not come with them. I used the bracket that was from the old regulator but will likely build a new one when I get back home so it is more secure. Excellent American made product and it allows way more propane through. I can run the propane heater, hot water, and all three burners on the cooking stove.

Great flow for multiple devices running simultaneously. Good price. Easy install. Exactly as advertised and shipped with care. However, 4 starts are due to manufacturing issue - product has a problem where the gas indicator will stay green, even if the supply tank is empty. So there's only notification (red) when BOTH tanks are empty. While I like the add-on pressure gauges all of them have a flow restriction; which is why I selected the high flow auto crossover.

Probably overkill on replacement of standard equipment but original one failed and this was almost same cost.

Slowed down pressure to half after two weeks and stopped working completely after 5 weeks. Could only return for one month.! Took it to propane distributor and they said diaphragm was faulty. Now have to purchse another one. $50 bucks out the window.. Grrr!..

I bought this one because it exactly matches the broken one except there is a 22 year difference in age and the company has changed hands at least once. The cool thing is that the existing mounting bracket works great.I am giving three points because the mounting holes are not threaded and there is nothing in the description that indicates that or what fastener one might use to mount it. I realized that the mounting holes don't come that way intentionally as when I pulled off the existing regulator (held on with two screws) the unused holes were smooth. Turns out I had a 8-32 tap laying around so I tapped the holes and was on my way with the existing screws.One reviewer recommended using #10 self taping screws and before the project, I purchased a 10-24 tap and 10-24x 1/2" screws. I decided practice on the old regulator and broke the tap. I am not a machinist clearly. I do think #10s would work but it was removing a lot of metal and the walls were getting thinner than I would prefer.I tested the regulator and all is well (much better than the leaky one that didn't want to auto-switch.) The stove seems easier to light and the flame is very consistent. I am going camping in 3 weeks and if something bad happens, I'll update this. I am looking forward to seeing if my refrigerator or catalytic heater work any better.One more thing...I didn't know the regulator was failing as I purchased the camper used 8 years ago and everything seemed to work. I don't know what the service life of these are but it might not be 22 years.
