I see that you have already recieved many replies. I use the Coleman Roadtrip. It out performs the others. The BTU output is much higher than most others.
Concerning the roll out grill idea. I have seen some, but I have also seen the fiberglass siding that had been melted on coaches where the grill wad too close. Not a pleasant sight. Also very expensive to repair.
I hope that you are enjoying the RV loif style.
