The cowling need only be removed if you are going to use the heating on gas not if using electric. If you set the temperature on the control panel below the ambient temperature then the heating will not come on but you will be able to heat the water by ensuring that you switch the tap symbol to "on". Hope this makes sense.....it's a lot easier to demonstrate than describe in writing!! 

good luck with all endeavours.

If when towing as I think you described in your first trip the outfit seems to "wallow" or jerky, check out your nose weight, don't buy expensive gauges, use a bathroom scales and  piece of wood  or round metal tube and then read nose weight on scales, will help any snaking/wallowing that may be induced in travelling, I found that as we built up our stock of essentials !the total allowable weight soon became borderline , so a radical slimming exercise followed by regular nose weight checks got rid of the extra essentials and improved the handling. Plenty of videos on this on you tube etc. Enjoy.

Thanks all for replies.with regards to nose weight etc when I wrote it was jerking It was when we just picked up caravan for first weekend away so was pretty empty but I found once I attached battery gas bottle etc and coming back it was behaving better.so as we not away for two weeks thanks to all your help I can now get the caravan and myself ready for next time so I'm better equipped lol thanks all again. It really is helping .
