I've been reading a lot of old propane threads, and I am still confused.
I have a 100-lb propane tank and 3x 20-lb propane tanks, all hung underneath my bus. Currently, they aren't connected to anything, but I want to run the following:
1. Honda EU3000IS generator with propane conversion kit
2. Propane Heater
3. On-demand hot water heater
4. Propane stove/oven
Additionally, I want flexibility to add additional propane components (second generator, propane fridge, etc.).
So, how do I do this? Where does the regulator go in the system? Is it right next to the tanks, before the lines split off for the appliances? If so, do I have to worry about not having enough pressure if I run more than one appliance at a time?
My thought was to do two two-stage auto-changeover regulators (one with 2x 20lb tanks, the other with one 20lb and one 100lb), connected by a y-valve. (I can turn off one set of tanks and use the other. Also, if a regulator goes bad, I still have a spare). Is this a bad idea?
Should my disconnect valves be right at the manifold under the bus? At the appliance inside? Should I have a valve on each end of the line?
Thanks!
