Options for propane regulators

I have the mixing valve that automatically switches over. Its leaking and also has a bad hose. Trailer is only 5 years old. My friends tell me the regulators are junk and fail often.

Is there a higher quality brand lots of people install?
Buy cheap and replace every couple years?

Was considering ditching the mixing valve all together. Does a regulator designed for propane BBQ work at the same pressure as an RV?

For the OP. Make sure what ever you get for replacement hoses have green acme nuts to connect to the cylinders. Hoses/regulators for BBQ grills have black acme nuts which are for low flow since they are servicing only one appliance. Hoses with green acme nuts are for medium flow and used typically on travel trailers because you may be running furnace, water heater and oven simultaneously. Hoses with red acme nuts are for high flow. Typically used with appliances that have large burners or multiple appliances run simultaneously requiring lots of propane.


Did not know that. Thanks for the info!

I got sick and tired of one-unit regulators and replaced it with 10 lb regulator then an 11" water column regulator. Several decades no problems.

Thanks, time2roll. No plans for remote sensor. I think I can glue this cap on permanently with no consequences. Or maybe seal the peephole.

What is the purpose of that plastic cap on the very top of Marshall? It says "Do not remove", and comes off easily - too easily. There is a small hole in the metal body underneath. Not sure that plastic will last long in the hot sun. Not very smart design, this part.
There is a remote accessory to pop on there.

I really like our Marshall as it would tell if one or both tanks were empty. It turns half red when the primary tank is empty, and all red if both are empty, or backup is turned off.
Odd feature to tell you when both are empty because I want to know when one is empty. That little window was very hard to read with fractions of a millimeter to determine the primary cylinder is empty. As I sad it was hard to hit correctly and I was often short or long in getting the cylinder filled. BTW no regulator indicator is needed when both are empty because at that point I just know.

Hey i dont mind off topics. Got any bbq recipes??

Someone mentioned wd40 on the swivel connection. Thats interesting. Does it clean away dirt and allow the metal on metal connection to seal again? Im currently boondocking and ended up hot gluing the sucker last night. It sealed when i first checked. Should go check it again.

Here is another question.
How often do you think the fridge cycles on propane? Because if my hose was leaking i would turn on the propane for a bit to cool the fridge, then shut it all down and not open the door. Lets say its 60 or 70F outside. How often and for how many minutes would you open the propane and turn the fridge to ON?

Have not stood and watched for the switch but it has never been in a middle position. Seems to snap into place.
