We have three Asdas in Warrington the only one without a height barrier is the one with the pay car park - result most motorhomers go half a mile down the road to Sainsburys or up the A49 to Morrisons - vote with your wheels and wallet. Twooks mentions IKEA, their next door neighbours M&S have the most stupid and dangerous car park, you are more or less pushed into driving in and reversing out. This is bad enough in a car (refer to IAM /ROSPA) but in a motorhome well !!
