Ok...you can thank me later. All of us lazy people who don't want to adapt the weber or don't care for the coleman......
Google the Napolean 285 Pro bbq.....not travelQ 285 and not 285x just 285 PRO. Canadian made and ready to go! It comes with a 3/8 end for attaching a regulator hose to propane. Just screw in a 3/8 end hose with your quick connect end for your trailer and DONE. no messing around with adaptors. Its same price as the Weber (maybe 20$ more) and connected to the low pressure on trailer gets to 450 degrees in about 5-7 minutes. We just hooked it up and works great. I'm getting rid of the Camp CHef now.
YoYou are welcome.
