There is no need to buy a new grille or modify an existing grille. Every RV has both a high pressure side (before the regulator) and a low pressure side (after the regulator).
If your grill uses a regulator AT the grill, then install a T with a quick connect fitting BEFORE the RV's regulator (between tank & regulator). If your grill does not use a regulator at the grill, then install a T with a quick connect fitting AFTER the RV's regulator. Not rocket science.
To the OP; simply install a T with a quick connect fitting anywhere AFTER your RV's regulator; where ever it is convenient.
