All I can say is, "Good luck." That hook up does't play nice. I've been trying to get a Coleman camp stove hooked up to the same gas port. I was able to finally fabricate a line that had both end connections to match. I purchased the Coleman regulator separate and cut the regulator part off and used the connection to the stove. I then cut the rubber hose that had the connection for the trailer.
End result? didn't work. The pressure regulator on the camper didn't match the required pressure on the camp stove and the flame blew out at the slightest puff of wind. The camper produced pressure too low for the stove. So, I'm back to using the 1 pound propane bottles from WalMart.
Meanwhile, about the only way to run off the propane tank on your camper is to put a T at the tank and before the regulator so the regulator that came with your grill will still work.
The regulator at your propane tank in your camper is a very low pressure. Chances are, even if you get the connection, the grill still won't work. And definitely, if you are using the regulator that came with the grill and the regulator with the camper, I promise you, it won't work.
I'm still frustrated, but using the 1 pound bottles until this Summer rolls around and I can mess with it again.
