Utility Tents on Non Awning Pitches

We've just changed from caravan to motorhome.  We know that you can't erect an awning or extend a sun canopy when a caravan is booked on a non awning pitch but we're not sure about the rules for motorhomes.  

We've just bought our our first motorhome and have bought a utility tent to store boots, coats, cadac etc when on site.  This will sit at the back of the pitch next to the motorhome.  When on a non-awning pitch would we be allowed to erect the utility tent where a car would normally be parked at the side of a caravan?

Thanks in antipation of all advice offered.
