I would stop you to shake your hand and ask you where I can get one...
I bought mine from Ebay last year, what is nice is that it sits in the back window but yet when I look at it in the rear view mirror the words are all in the right direction, no it doesn’t cover the whole window, just the area right behind me, its an extended cab.
But I do think I have had encounters with some irate people but like my day job where I drive a concrete mixer my truck is an 8,000 lb Dually and size DOES matter.
And I am thinking about getting a vinyl decal of at least a foot square or larger and putting it on the drum of the truck.Could you just imagine if it was on the whole drum?
Would have to be on both sides as one side would always be upside down as it turns, kinda like a distress flag?
I swear if I had a bit of disposable income I would have a couple of thousand bumper stickers made and hit some car parks or shopping centers, that would indeed be a riot.
