I take it you have a good working stove and burners are just not as powerful as you would like. Our 2013 has Wedgewood/Atwood with 6,500 btu burners in rear. The front burner is a 9000 btu which they call "high output". On our 2001 RV has regular burners, we can tell the difference.
One option might be to see if your could retrofit/install a "high output" burner. Worth a phone call to manufacture see if possible and other questions it might effect such as supply lines, burner valves etc, should be asked at same time.
