Accessing the propane line December 15, 2018, 07:51:40 pm We all do things a little bit different. Two of the pictures show adding a propane port to the high pressure side of the propane line without moving the regulator and having to modify the original copper line from regulator to coach. Teflon tape not recommended for propane lines as tape bits may get into the regulator but I got away with it.The other picture shows adding the inside propane line to an RB. Access to the propane line was at the furnace fitting. The original plan was to face the quick disconnect down but I drilled the hole a 1/4" too low and couldn't open the power panel. So much for planning ahead. I tend to run the heater at the front so it works.The tough part was finding the bulkhead brass fitting. Can't remember where I got it but it took some searching.

Re: Accessing the propane line Reply #2 – December 15, 2018, 10:02:49 pm It was to run a backup Honda 1000, converted to propane, generator. Another mis-judgment. When charging from the generator my initial charge rate is 130 amps into the lithium and lead acid batteries which is pushing 1800 watts. The small Honda can only power the 40 amp lead acid charger. The port can be used for the extend a stay type hookup. I have that fitting now, the picture is old. I expected the Honda to be able to run one 60 amp lithium charger. It cannot.I'll probably leave the Honda home on this year's travels unless the Onan acts up. It has failed me twice in 12 years. I'm always off grid now and in the RV from the end of February to the end of September in cold country. The generator is important as I only have 200 watts of solar with satellite TV and Blu-ray player. Both battery banks are at 100% by 5PM every evening, rain or shine, with a 30 minute generator run. Power is no longer a problem.

Wouldn't an Extenda-Stay fitting have done the same thing?Not so very long ago I had and Extenda-Stay connection plumbed into the line at that exact same point. It not only feeds the RVs regulator but one leg feeds another 14# regulator which supplies LP into a curb side compartment where I use it to feed my BBQ grill. The 3rd leg of course is used when connecting a bulk tank.
Re: Accessing the propane line Reply #4 – December 16, 2018, 12:53:13 am Maybe. I think the Extenda stay would move the regulator an inch or two to the right requiring changes to the coach plumbing and a different mounting point for the regulator cover. I didn't want to do that.

You do what you have to do.Propane regulator change | FlickrPipe dope is an appropriate sealant and is gas rated.https://www.homedepot.com/p/Oatey-8-oz-Pipe-Joint-Compound-154202/100204007I understand the need for power in the winter but wonder why not install a roof full of solar panels and not worry so much about it? You wouldn't need to carry the Honda and this would reduce the propane consumption considerably.With a 1800-watt charge rate, you should be using a 3000-watt, or bigger, generator. The existing 4000-watt Onan would be a suitable choice. Trying to squeak by with an undersize generator is a recipe for failure. If, for some reason, the Onan refuses to run, the engine's alternator can provide a high charge rate and doesn't use a lot more fuel, per hour, than the generator does.Larry
Re: Accessing the propane line Reply #6 – December 16, 2018, 02:49:11 am No room on the roof. (Maybe for a 100 more watts.) I'm not trying to run the A/C from the battery. It will run the microwave but I prefer the generator. All I need to run is my heated mattress pad, everything else is 12 volts but there is always something that needs a little AC to charge. The 1500 watt inverter was the smallest Samlex had that was made with the three wire connection for the house wiring through a transfer switch. The big current draws are sat TV and the furnace.I have been using a 110 volt Blu-ray but it is soon to be replaced with a 12 volt version. Just gotta get it out of the box.With 225ah of flooded lead acid and 200ah of lithium I figure it equals 600ah of AGM. Thirty minutes of generator a day is trivial for 100% battery every evening. I'll worry about how to charge without the Onan when it craters. I expect I can keep it running. The Honda stays home this year. No room. It was originally bought to drone on for hours charging lead acid. I found a better way.Some days sun is enough but parking in narrow mountain canyons with afternoon showers shuts it down.
