The Flame appears to be the same but I haven't cooked with it yet. I installed quick connects on the original regulator so I can used the little green bottles too.
Can you show more detail?
I installed 1/4-20 x 1 1/2" bolts in place of the originals, the a nut for a spacer then the bracket.
IMHO the grill is too close to the fiberglas. Maybe you could extend it 4-6" or add a heat shield.
The Q runs hotter than stock RV grills.
I installed a cable stop otherwise the lid would rest against the metal bracket attatched to the trailer. I have about 3 inches. I agree that it may be too close, I'm going to monitor it closely and add a shield if necessary. I didn't want to extend it too far, it's pretty heavy.
I used Mr. heater fittings. I had to modify the male connector. There are photos on my profile page.
