masetheace:
should be plenty of space on heathfield industrial estate, often see lorries parked up overnight on Cavalier road, there is a spar and chinese/chip shop nearby. This estate is just off the a38 so not strictly in newton abbot (about 4 miles away). Depends where your drop is and if you must be in newton abbot overnight, cant think of any obvious hgv parking, you may get a space on Brunel Ind est which is by the railway station as Sunday would be pretty quiet down there.
Thanks parked here as it turned out I was delivering to this estate. Only thing, Chinese/chip shop not open on a Sunday!!
