Decent description of the process to convert an appliance with a separate regulator. The Coleman Road Trip grill - unlike the common lightweight camp stoves of any brand - is readily converted because the regulator can be removed, leaving the flame control (on the front of the appliance) in place. Common stoves (Coleman and otherwise) combine the regulator and flame control into one device, so this approach doesn't work for them... even if you can find a point along the plumbing where the connection is a common pipe thread instead of something proprietary.
I note that if you have a Road Trip and you're willing to buy an extra set of the plumbing bits that Coleman puts on the back, you can have two easily interchanged setups,
- one for use from high pressure (from a one-pound cylinder or from a bulk tank with a hose and adapter) and
- one for use from low pressure (through a quick connector).
The disclaimer on the front of the second YouTube video is priceless.
One minor caution if following the first YouTube video: plumber's thread seal tape is PTFE, not silicone as described. If you need to be told this, or if you don't know to use yellow (thicker) instead of white (thinner) plumber's tape, I think you should probably do a little more research before actually building a rig like this.
