Would this be an acceptable model: Marshall Excelsior MEGR-253H ?
Thanks again for your quick replies!
Marshall is OK. MEGR-253 (without thd H) should be all you need. It gets be by running the stove, furnace and water heater all at the same time. MEGR-253H (high flow) is probably for vending trailers.
The acme nuts on hoses for travel trailers are green which is medium flow.
Black acme nuts are low flow for BBQ grills, outdoor cookers and single appliances, etc.
Red acme nuts are high flow. There is a Papa John's here that does vending at the shipyard here in Newport News and I think it is also used at events. They have a trailer that has 6 - 30 lb cylinders on the tongue and all the acme nuts are red. I looked it over in their store parking lot. I believe it also has the Marshall high flow regulators.
