I dont know if anyone really heard of it yet, but i just decided to check for the movie trailer online and i found it.
The red 87 chevy c2500 landscaping truck was mine(my gf's before that) which they borrowed along with the trailer and the lawnmowers for the landscaping scenes. Its in the trailer, right at the beginning and further in.
Its pretty cool to see all those famous people in my truck, I sold the truck to my old boss last year right when they finished filming with it. now i gotta see the movie
