I agree with Nick ( and I must admit I don’t usually lol) as you obviously do not know the reasons or the cure for your problem hire the services of a suitably qualified gasfitter who is experienced with mobile homes and LPG.
Remember …………Gas can kill so don’t play with it or rely on electronic devices to save you as they are only warning devices nothing more!!!!!!!
