The key to look at is are you tapping in before or after the main regulator.
- If you tap in before, you use your grill as normal with it's own regulator. While you always want propane connections well sealed, these will be more critical due to the higher pressure they must contain.
- If you tap in after, you need to be able to remove your grill's regulator as two regulators in series will pass little to no gas to your grill.
The typical RV tap is after the regulator.
On some grills, it's simple to eliminate the grill's regulator. On others, the temperature control and regulator are combined into a single device, so you need to find a non-regulated temperature control (not always easy).
