I improvised one day many years ago and it is still in place. I had an old landscaping timber standing in the corner of the garage and two bags of readymix cement laying there that had got wet from snow dripping off the vehicles. Needless to say they readymixed themselves and are now bags of cement. Put the truck where I wanted it then slid the timber in place in front of the wheels. Backed the truck out and put the bags of concrete in front of the timber. Never moves and I am on the 3rd truck since I put it there. Not pretty but very effective.
