Propane blockage
I have recently purchased first trailer and is bit of a fixer upper so I am fairly new to this. I have been trying out everything to see what works and does not work. I tried turning on my furnace, wa...

Another thing to realize, the large green ACME nut at the LP tank has a flow restrictor in it. That is assuming your camper is new enough to have the green nut and not an all brass left hand thread fitting. Your stand alone BBQ grill has these, the nut is black, they change color for BTU capacity.
The green nut is a safety feature to protect the system from a blown hose, valve etc and letting the system run wide open. If you turn on the gas valve at the tank too fast, it will accidently trip the safety and extremely restrict the gas flow. This can and does happen all the time on a completely working system. You have to open the gas valve, very very slow, hear the gentle hiss, wait for the hiss to stop, then you can open the valve all the way until it stops.
If you tripped the safety, turn off the gas valve, unscrew the green nut, that will release the pressure and it resets the excess flow valve in the nut. Put it back on and try again.
That may have been part of the problem from the start if you did not realize this. Just cranking the valve open will have high odds of tripping this excess flow safety.
Hope this helps
