Stevenage, daytime parking

Evening everyone
This might seem a bit odd, but is there anywhere in or around Stevenage to park a LGV during the day? I know where to park at night, but daytime is a problem.
Hope you can help.
Cheers

Just to let you all know…
Parked up near to a business area at 01.00h, thieving bar stewards had liberated box of tools, spare bulbs etc by 02.00h. And I was asleep in the back!
Plod were very helpful, but, “sorry sir, not much we can do to help you. Just park in near to the CCTVs in future”
Oh well, cab now empty when I leave it…
Cheers
Paul
