replacement "outside" stove for 09 passport

[slopijom]

Hi,
I have an 09 Passport with the outdoor stove that slides out of the wall. im looking for a better replacement. Does anyone know if i can get them with the plastic mount and slide assembly? Or would i just have to modify the plastic mount to fit whatever stove i find. im looking for a stove with two big burners instead of the one big and one small burner...

thanks,
Harry
