Okay, got my hose setup for my grill from the local LP business and it doesn't work....
I had a "T" made so I could connect the Coleman Road Trip grill and still connect my Kodiak stove at the same time...
Problem #1 was that the male quick connect end from the LP business (on the "T") has a larger inside diameter than the male end on the Kodiak stove. The larger diameter did not press in the plunger to release the propane from the female quick connect on the trailer. So I went to my local RV dealer and got the right male end. Now it connects fine and releases the propane.
(See the small blue tipped end in the picture).
Problem #2 is that the female quick connect end from the LP business (on the "T") does not work with the male end from the Kodiak stove. Now I have to get a new female end from the RV dearer and swap them out on the "T". (See the larger blue end in the picture).
Problem #3 is that the Coleman Grill has a special fitting on it with a regulator that connects the small propane bottles to the grill. The regulator on this fitting does not like the low pressure propane coming in from the quick connect (which already regulated on the 20# drums). The burners light, but just barely stay lit on HI. So now I have to get in touch with Coleman and see if they sell a connector without a regulator on it...
Long story short, I've invested $68 for the setup from the LP business and another $12 from the RV dealer and still don't have a working setup. And it will cost another $15 to get the right female end from the RV dealer... and unless Coleman carries the part I need I won't be spending another $15 for a part that I won't need...
