I have the COLEMAN ROAD TRIP and it does just great for us. Has two work ends and top grill hood. It also has a water reservoir just under the burners that makes it so easy for clean up. Mine has a nice tote with two wheels with storage space for several different grill tops. This is a two burner type and uses 1LB propane canisters.
I am not a fan of having my grill right next to the my popup trailer wall. I like to have it at a right angle to the trailer.
My trailer has a grill hookup but I have never used it. The 1LB propane canisters do just fine for us and will last several days when camping. I also have a MR BUDDY heater that uses the 1LB Canisters so always have a supply on hand.
Everyone really likes the WEBSTERS and I suspect they seal up better with their lid arrangement.
Have cooked a many meals on my ROADTRIP... No complaints...
