Having taken the front off our fire so many times to cure this rattling i wonder whether there is any other thought on this apart from turningradio up.I have bent the fins so none are in contact then place a sleev around top of gas control rod as that was near the caseing, fited plastic sleeving over those wire ratainers. It seems as if the rattles come from the RH side near the middle where nothing is!. Any futher idea's welcomed.. Thanks.

I assume we are talking motorhome here. It is the one drawback of them that either the oven or the fire seem to rattle irritatingly despite towels etc.
If you have taken off the front I assume you have checked everything inside to see if anything there is making the noise, but getting carried to where you hear it. Try leaving the front off and see if there is any difference. If so, then the front itself is the cause and possibly you may need to get a new one, if you cannot see any obvious faults. It may be not attaching itself to the securing clips fully. If leaving the front oiff does not improve the situation, then more digging will be required.
Sorry, not to be more help but it will be a case of remove a bit and check.

If it is only rattling when the burner is operating, it may be burner pulsation. A service and combustion check may cure the problem?
Try putting a small screw between the top vent and drill through to the cabinet, my dealer did this to stop the heater from jumping off its mountings when towing.

Sorry, I may have misunderstood the OP. I thought he was talking about rattles while driving, especially as he mentioned turning up the radio.
Are you sure it's the front case rattling? Mine used to rattle and a quick thump cured it - for a while. I found that it was the fan rattling and effected a cure for it as follows:
Truma Fan - curing the rattle
I found that our Ultraheat would vibrate loudly when the fan reached certain speeds. This was found to be because the fan was not held tightly to the back panel of the heater. This was due to the clips being loose in their mountings. Tightening the clips has cured this, using the following procedure.
1. Remove the ducts from the diverter on the lower part of the fan assembly. The ducts will be held in by a self-tapping screw. Unplug the fan control cable and the 12v leads, making careful note of the polarity
2. Remove the fan from the back of the heater by loosening the 3 screws and lifting the fan unit up.
3. Check that all of the panel screws on the heater are tight
4. Remove the 3 metal fan mounting clips in the rear panel of the heater
5. Carefully, bend the prongs outwards then bend the top of the prongs back in so that the screw will prise them apart when inserting
6. Put a screw in the clip for a couple of threads and reinsert the clip. Screw this in leaving about 8mm proud
7. Do the same for the other 2 clips
8. Take this opportunity to clean the fan
9. Remove the diverter (held on by 2 torx screws)
10. Clean the fan blades thoroughly using a small test tube or awning rail brush and a vacuum cleaner and clean around the motor
11. Reassemble the diverter
Reassembly is the reverse procedure.
Test by turning the fan onto maximum on auto and switch on the heating. The fan should increase speed to maximum. Alternatively, set the fan to manual and slowly increase the speed of the fan to check if the rattle has been cured.
Hope this helps.
