I have a Coleman RoadTrip grill that instead of using those small propane bottles (1 pounders) I want to hook on to the attachment that came with my fiver and use the propane from the RV. Now the propane has a regulator for the coach and my grill has a regulator on the grill for the small bottles. Is this going to be a problem? Camping world says it would be ok but I just wanted to find out if anyone has done this with now problems. Thanks, Bill
