I tried to find some info but wasn't doing well until I hit Google Images. It looks like the propane bottle mounts off to the side on a long thin pipe. If you can remove the regulator (which appears to be mounted to where the bottle mounts), you can probably find some parts to make up a connection to your RV. I'd never heard of that grill before but it sounds like a pretty cool little thing. Good luck.
